Background

In the design and simulation process of the quantum bit, a method of electromagnetic calculation is needed to extract quantum circuit parameters and calculate the distribution of an electromagnetic field in the environment to analyze decoherence of quantum states. Accurate and efficient electromagnetic simulation can effectively help the design of the quantum chip, and the bit with high phase-fading coherence time is realized through the design.

In the related art, the current simulation of qubits mostly adopts a finite element method for calculation. The finite element method needs to perform three-dimensional mesh subdivision on a structure and an environment in electromagnetic simulation, and solve a large-scale matrix equation. During mesh generation, the structure and environment can be divided into a large number of three-dimensional structures, such as tetrahedrons. The material parameters in the structure and environment will be defined in each tetrahedron, thereby achieving a more accurate description of the environment. And taking the limited number of tetrahedrons after subdivision as the minimum unit for bearing the electromagnetic field, and substituting the minimum unit into Maxwell equations for solving. However, when the above-mentioned solution is adopted to solve the problem, a large number of minimum units are generated due to the subdivision in the three-dimensional volume designed by the method, which results in a large number of calculated unknowns.

In view of the above problems, no effective solution has been proposed.

Under the operating environment described above, the present application provides a qubit processing method as shown in fig. 2. Fig. 2 is a flowchart of a first qubit processing method according to embodiment 1 of the invention, which, as shown in fig. 2, includes the following steps:

step S202, determining a plurality of parts included by the qubits;

step S204, determining electromagnetic interaction among the multiple parts by adopting an integral equation to obtain electromagnetic parameters of the surfaces of the multiple parts, wherein the integral equation respectively adopts a Green function to represent the electromagnetic interaction among the multiple parts;

step S206, the electromagnetic parameters of the surfaces of the multiple parts are summed to obtain the electromagnetic parameters of the qubits.

Through the steps, the electromagnetic interaction among the parts is determined through an integral equation in a mode of determining the parts included by the qubits, so that the electromagnetic parameters of the surfaces of the parts are obtained, the parts are respectively and efficiently processed, and the electromagnetic parameters of the surfaces of the parts are summed, so that the purpose of obtaining the electromagnetic parameters of the qubits is achieved, and the technical problems of large calculation amount and long calculation time in the simulation process of the qubits in the related technology are solved.

As an alternative embodiment, the portions comprised by the qubit are determined. For example, in a quantum chip, the quantum chip may be divided at a physical level, that is, a core design of the quantum chip may be divided into a plurality of portions (for example, including two plates constituting a qubit, a control line, a ground, and the like), and the plurality of portions belong to the same flat layer, so as to design and determine the plurality of portions included in the qubit; the division may also be performed by other layers, that is, the user may perform the division according to the functions executed by each portion, or may perform the division according to the location where each portion resides, which is not limited herein. By determining the parts included by the qubits, a basis is provided for subsequent respective calculation of the parts of the qubits, so that the single calculation amount is reduced, and the calculation is simpler.

As an alternative embodiment, the electromagnetic interaction between the plurality of portions is determined by using an integral equation to obtain the electromagnetic parameters of the surfaces of the plurality of portions, wherein the integral equation is used to characterize the electromagnetic interaction between the plurality of portions by using green's functions, respectively. When the integral equation is adopted to confirm the electromagnetic interaction among the multiple parts, the integral equation can represent the environments and structures of the multiple parts, and the integral equation can be flexibly selected according to different representation capabilities of the integral equations or different environments and structures with respective emphasis. The electromagnetic interaction between the parts can be described numerically by constructing a matrix by an integral equation. For example, a matrix can be constructed by using a green function, an integral equation corresponding to a plurality of parts can be determined by solving the matrix, the green function can represent the structure and environment of quantum bits at the corresponding parts, and the subdivision of a two-dimensional grid is performed, so that the electromagnetic parameters of the corresponding parts can be obtained. The electromagnetic parameters are obtained by calculating the integral equation of each part, and when each part is calculated, the position quantity and the number which need to be calculated are greatly reduced, so that the calculation efficiency is effectively improved.

It should be noted that the electromagnetic parameters mentioned above may refer to various relevant parameters related to the qubit, such as the electric field energy of the local loss region of the qubit, the electric field energy of the entire spatial region of the qubit, the occupancy ratio of the electric field, i.e., the ratio of the electric field energy of the local loss region to the entire spatial energy, and so on.

As an alternative embodiment, when the electromagnetic interaction between the plurality of portions is determined by using the integral equation to obtain the electromagnetic parameters of the surfaces of the plurality of portions, the following manner may be adopted: respectively carrying out two-dimensional mesh subdivision on the surfaces of the parts to obtain a plurality of meshes and obtain a plurality of meshes; and calculating the electromagnetic parameters of the grids by adopting an integral equation to respectively obtain the electromagnetic parameters of the surfaces of the parts. And carrying out operation of an integral equation by a plurality of grids obtained by carrying out two-dimensional grid subdivision on the surfaces of the plurality of parts to obtain the electromagnetic parameters of the surfaces of the plurality of parts. The electromagnetic parameters of the surfaces of the parts can be acquired more accurately and quickly.

As an alternative embodiment, performing two-dimensional mesh generation on the surfaces of the plurality of portions to obtain a plurality of meshes respectively includes: and respectively carrying out two-dimensional mesh subdivision on the surfaces of the parts by adopting a mode of mixing a uniform thinning method and a boundary thinning method to obtain a plurality of meshes. When any scheme of uniform thinning or boundary thinning is adopted, the problem of quantum bit simulation cannot be well solved: only adopting uniform thinning will lead to the rise of unknown quantity index, increasing the calculation burden; only adopting the boundary refinement will result in that the calculation accuracy of the non-boundary area cannot be well controlled. Therefore, the uniform thinning scheme and the boundary thinning scheme are mixed, so that the characteristics of the grid can be well maintained.

As an optional embodiment, a method of mixing a uniform refinement method and a boundary refinement method is adopted to perform two-dimensional mesh subdivision on the surfaces of a plurality of parts respectively to obtain a plurality of meshes, and the method includes: and respectively carrying out two-dimensional mesh generation on the non-boundary areas of the surfaces of the parts by adopting a uniform thinning method, and respectively carrying out two-dimensional mesh generation on the boundary areas of the surfaces of the parts by adopting a boundary thinning method to obtain a plurality of meshes. A uniform thinning method is adopted in the non-boundary area, a small number of uniform thinning layers are adopted, the precision of the non-boundary area is effectively optimized, and meanwhile the number of unknown quantities is effectively controlled; and a boundary thinning method is adopted in the boundary area, and the mesh subdivision at the boundary is randomly thinned in the vertical direction, so that the calculation accuracy of the boundary can be greatly improved, and meanwhile, the unknown quantity is linearly increased and controlled in a smaller range.

As an optional embodiment, the mesh obtained by subdivision is a triangular mesh, and the aspect ratios of the triangular meshes obtained by subdivision by adopting a uniform thinning method are consistent; when the triangular meshes obtained by subdivision by adopting the boundary thinning method are closer to the boundary of the boundary area, the obtained triangular meshes are smaller, and the length-width ratios of the triangular meshes are inconsistent. In the uniform refinement method, the aspect ratios of the triangular meshes are consistent, and a plurality of small meshes with consistent aspect ratios can be generated through multi-layer refinement, so that the conformality of the meshes can be maintained, and the structured processing is facilitated; in the boundary refining method, when the grid is close to the boundary, the grid is gradually reduced, and the singularity at the boundary can be better represented. By adopting the two methods, the grid can be kept conformal locally, and the calculation precision can be improved while the unknown quantity is controlled.

As an alternative embodiment, the electromagnetic parameters of the surfaces of the plurality of portions are summed to obtain the electromagnetic parameters of the qubit. There are also many ways to sum the electromagnetic parameters of multiple parts, and a method of an integral equation is more often adopted, for example, a gaussian summation method may be used to perform summation to obtain the electromagnetic parameters of the whole qubit, thereby ensuring that the electromagnetic parameters of the whole qubit are completely obtained. For example, in a quantum bit decoherence scene, when the electric field occupancy rate near the surface of the quantum bit superconducting material is accurately calculated, the electric field occupancy rate in the ultrathin region can be calculated by adopting a Gaussian integration method, so that the problem that the surface energy density of the superconducting material is essentially divergent is effectively solved, the calculation is relatively accurate, and the calculation precision and efficiency of the electric field occupancy rate in the quantum bit can be effectively controlled. The electromagnetic parameters of the qubits can be obtained by simply calculating the electromagnetic parameters of a plurality of parts, and after the electromagnetic parameters of each region are efficiently and accurately calculated, the electromagnetic parameters of the qubits can be simply and accurately calculated, so that the calculation amount is greatly reduced, and the calculation speed is accelerated.

As an alternative embodiment, by dividing the core design in a quantum chip (qubit) into multiple parts: including two plates that constitute a bit, a control line, ground, etc. (of course such division is natural and will not be described here). Wherein the several parts belong to the same level inside the chip. And then constructing a matrix by using an integral equation method for the interaction among the parts, namely describing the interaction among the parts by using a numerical method. In the integral equation method, a green function is adopted to represent the structure and environment of each part of the quantum bit in the corresponding flat layer (namely the characteristics of the (electromagnetic) interaction of each part). In order to accurately obtain the numerical expression of the characteristics, the numerical value of each element in the matrix can be obtained by gridding each part and calculating the Green function of each grid after grid combination, so that a complete matrix is constructed. By solving this matrix and summing the charges of the various parts, a lumped effect of the interaction of the various parts can be obtained.

In a specific scenario, when examining the decoherence problem of qubits, the electric field occupancy near the surface of the qubit superconducting material needs to be accurately calculated. Under the scheme, the electric field near the surface of the superconducting material and the electric field occupancy rate of the superconducting material can be reconstructed, for example, the electric field occupancy rate in the ultrathin region is calculated by adopting a Gaussian integration method, the problem that the energy density on the surface of the superconducting material is essentially divergent can be effectively solved, and the calculation is accurate.

Therefore, the accuracy and efficiency of the electric field occupancy rate calculation in the qubit can be effectively controlled. Compared with other methods, the method adopting the embodiment and the optional implementation mode can greatly shorten the calculation time, remarkably improve the calculation accuracy and effectively control the calculation accuracy. The method solves the technical problems of large calculation amount and overlong calculation time in the simulation process of the qubits in the related technology.

step S302, displaying a quantum bit import control on an interactive interface;

step S304, responding to the operation of the import control, and displaying the image of the qubit on the interactive interface;

Through the steps, the leading-in control of the qubit is displayed on the interactive interface, the operation on the leading-in control is responded, the image of the qubit can be displayed, the electromagnetic parameter instruction of the qubit is received and responded to obtain, a plurality of parts included by the qubit are determined, the electromagnetic interaction among the parts is determined through an integral equation, the electromagnetic parameters of the surfaces of the parts are further obtained, the parts are respectively and efficiently processed, the electromagnetic parameters of the surfaces of the parts are summed, the purpose of obtaining the electromagnetic parameters of the qubit is achieved, and the technical problems that in the simulation process of the qubit in the related technology, the calculation amount is large, and the calculation time is too long are solved.

Based on the above embodiments and alternative embodiments, an alternative implementation is provided, which is described in detail below.

In the related art, the current simulation of qubits mostly adopts a finite element method for calculation. The finite element method needs to perform three-dimensional mesh subdivision on a structure and an environment in electromagnetic simulation, and solve a large-scale matrix equation. During mesh generation, the structure and environment can be divided into a large number of three-dimensional structures, such as tetrahedrons. The material parameters in the structure and environment will be defined in each tetrahedron, thereby achieving a more accurate description of the environment. And taking the limited number of tetrahedrons after subdivision as the minimum unit for bearing the electromagnetic field, and substituting the minimum unit into Maxwell equations for solving.

However, when the above-mentioned solution is adopted to solve the problem, a large number of minimum units are generated due to the subdivision in the three-dimensional volume designed by the method, which results in a large number of calculated unknowns. The finite element method has the following defects: the calculation time is consumed greatly; the singular electromagnetic field at the corner of the metal structure is difficult to accurately calculate; the above disadvantages make it difficult to achieve efficient qubit design automation.

In view of this, in an alternative embodiment of the present invention, a scheme for superconducting qubit simulation and electric field occupancy calculation based on electrostatic field integral equations is provided that speeds up superconducting qubit simulation and accurately calculates electric field occupancy in the superconducting qubits. The following is a detailed description of alternative embodiments of the invention.

Calculating the occupancy rate of the electric field;

for analyzing decoherence of qubits, it is often necessary to calculate the electric field occupancy, i.e. the proportion of the electric field energy in the local depletion region to the total spatial energy. The local loss region is often only a few nanometers, and the energy of the region can be efficiently and accurately calculated by an integral equation method. The method comprises the following steps:

s1, dividing the loss area into a plurality of flat layers by adopting a Gaussian quadrature method;

s2, calculating the energy density of each flat layer by using an integral equation;

and S3, obtaining the electric field energy of the region by using the Gaussian quadrature method for summation.

It should be noted that fig. 4 is a graph comparing efficiencies obtained by the method for calculating electric field occupancy according to the embodiment of the present invention, and as shown in fig. 4, the efficiency can be improved by more than 50 times by adopting the above scheme of the integral equation.

(II) calculating the energy density of each flat layer by using an integral equation;

when the integral equation is used for calculating the energy density of each flat layer, the integral equation method can adopt an analytic Green function as a representation function of the environment, so that meshing of a three-dimensional structure is not needed, and only two-dimensional meshing of the surface of an object is needed. Therefore, the difficulty of mesh generation is greatly reduced, the quantity of positions needing to be calculated is also greatly reduced, and the calculation efficiency is effectively improved.

The following is a specific example, taking the calculation of the capacitance between two pieces of metal as an example:

fig. 5 is a schematic diagram of a capacitance calculation method according to an embodiment of the present invention, and as shown in fig. 5, two pieces of rectangular metals 1 and 2 are placed on a dielectric substrate, and the capacitance between the two pieces of metals is calculated. Fig. 6 is a schematic diagram illustrating an effect of using an integral equation method and a finite element method in the capacitance calculation method according to the embodiment of the present invention, as shown in fig. 6, only a rectangular metal surface needs to be subdivided by using the integral equation, and a real space needs to be subdivided by using the finite element method in three dimensions. The reduction in complexity is significant.

Fig. 7 is a flowchart of a calculation for extracting a capacitance parameter in a capacitance calculation method according to an embodiment of the present invention, and as shown in fig. 7, after mesh division is performed on surfaces of rectangular metals 1 and 2 (as shown in a left part of fig. 7), the following scheme may be adopted to continue extracting the capacitance parameter:

s1, setting voltage difference, as shown in the middle part of FIG. 7, white metal 1 and black metal 2 represent that different voltages (potentials) are set）；

S2, solving the charge distribution, as shown in the right part of the figure 7, distributing corresponding different charges q on the metal 1 and the metal 2 with different voltages⁽¹⁾，q⁽²⁾(ii) a Wherein q is by solutionTo obtain a mixture of, among others,is a matrix constructed from the green's function. Q⁽¹⁾Is pair q⁽¹⁾Are summed to obtain Q⁽²⁾Is pair q⁽²⁾Summing to obtain;

s3, extracting the capacitance value according to the formulaTo obtain a capacitor C as shown in FIG. 7₁₁，C₂₁。

The above steps can be extended to multiple metals and ultimately solve for the capacitance C between each metal.

It should be noted that fig. 8 is a schematic efficiency diagram obtained by the method for calculating capacitance according to the embodiment of the present invention, and as shown in fig. 8, the efficiency can be improved by nearly 50 times by solving the capacitance with the above scheme of the integral equation.

And (III) refining the triangular mesh of the boundary of the non-conformal surface.

The optional embodiment of the invention also provides a non-conformal surface boundary triangular mesh refinement method, which is a mesh refinement scheme which is suitable for simulating boundary singularity and is easy to operate. The calculation of the electric field occupancy in the quantum chip is particularly effective.

In the process of solving the integral equation, a grid thinning method is used, and when a numerical method is used for solving a differential equation, grid subdivision needs to be carried out on the environment and the boundary of the solved problem. In such problems, due to abrupt change of boundary conditions, the solved quantity has singular values at the boundary, so that accurate numerical solution becomes extremely difficult, and when the loss of the quantum chip is analyzed, the electric field occupancy in an ultrathin region needs to be accurately analyzed. The general numerical calculation deals with such problems with exceptional difficulty.

In view of this, the non-conformal surface boundary triangular mesh refinement method provided by the optional embodiment of the present invention is adopted to refine the mesh subdivision of the boundary, optimize the mesh step by step in an iterative manner, and perform optimization approximation on any curved surface/plane to generate a conformal mesh. The gridding method provided by the optional embodiment of the invention is used for further optimizing the calculation expense of general grid subdivision in the application of the superconducting quantum chip, and can effectively solve the related problems in the field of excess quantum. The mesh refinement method provided by the alternative embodiment of the present invention is explained in detail below.

An alternative embodiment of the present invention will be described in detail by taking an example of refining a roughly-divided triangular mesh:

(1) uniform refining

Fig. 9 is a schematic diagram of a uniform refinement scheme in a mesh refinement method provided by an alternative embodiment of the present invention, and as shown in fig. 9, a plurality of small meshes with uniform aspect ratios can be generated through multi-layer refinement. The triangle adhered to the surface is divided into four small triangles by adopting uniform thinning. This uniform refinement can be used multiple times. The conformality of the grid can be maintained. If the scheme only works on boundary triangles, a non-conformal mesh will be produced. Meanwhile, the number of triangles increases exponentially with the number of refinement layers.

(2) Boundary refinement

FIG. 10 is a schematic diagram of a boundary refinement scheme in a mesh refinement method according to an alternative embodiment of the present invention, in which triangles are divided parallel to boundaries and the heights of the triangles are guaranteed, as shown in FIG. 10Satisfy the requirement of /Constant number>1. When the grid is close to the boundary, the grid is gradually reduced, and the singularity at the boundary can be better represented. The triangle of the boundary is divided into a plurality of smaller triangles by adopting a gradual attenuation scheme. Meanwhile, the grid can be locally conformal; the number of the grids is linearly increased along with the number of the thinning layers, namely the number of the triangles is linearly increased, and the length-width ratio of the triangles is gradually changed.

Only one scheme of the uniform thinning or the boundary thinning is adopted, and the problem of singular point simulation cannot be well solved: only adopting uniform thinning will lead to the rise of unknown quantity index, increasing the calculation burden; only adopting the boundary refinement will result in that the calculation accuracy of the non-boundary area cannot be well controlled.

Therefore, the mesh refinement scheme proposed by the alternative embodiment of the present invention is to mix and use the uniform refinement scheme and the boundary refinement scheme, so that the characteristics of the mesh can be well maintained.

In the guidelines of the superconducting quantum chip, only electrostatic field analysis of the planar structure is usually required. The optimal approximation to an arbitrary surface is therefore not important and involves additional computational expense. Meanwhile, the non-common grids are also suitable for electrostatic field analysis.

Through the above optional embodiment, the following beneficial effects can be achieved:

(1) the simulation of the superconducting qubit is accelerated;

(2) accurately calculating the electric field occupancy rate in the superconducting qubit;

(3) in the grid thinning method, a small number of uniform thinning layers are adopted, so that the precision of a non-boundary area is effectively optimized, and meanwhile, the number of unknown quantities is effectively controlled;

(4) in the mesh refinement method, mesh subdivision at the boundary is randomly refined in the vertical direction, the calculation accuracy of the boundary can be greatly improved, meanwhile, the unknown quantity is linearly increased and controlled in a smaller range.
