Abstract
Description
Technical Field
[0001] The present invention relates to the fields of quantum computing, quantum information manipulation and AI intelligent technology, and more specifically, to a method for determining an optimal strategy for a quantum gate experimental process, optimizing a quantum circuit search scheme, determining an optimal number of experiments for quantum information storage and manipulation, and software development and application of an intelligent decision support system for a quantum information manipulation process. Background Art
[0002] In the process of quantum state manipulation of microwave photons to achieve quantum state transformation, the optimization of large-scale quantum information manipulation schemes is very important, as it can improve the efficiency of quantum computing fidelity estimates during the transmission, processing and detection of quantum information. There are three major challenges in the optimization of large-scale quantum information manipulation schemes, quantum information fidelity manipulation experiments and quantum computing: first, how to optimize the quantum gate experimental process and quantum circuit search scheme under uncertain conditions; second, how to give the corresponding optimal number of experiments around the quantum information manipulation experimental process under uncertain conditions; third, how to optimize the large-scale quantum information manipulation process from a software perspective, transform a physical system into a quantum processor through an intelligent decision-making system, and achieve the optimal quantum information manipulation process.
[0003] At present, in related research, some adopt the empirical approach of repeated practice, and there is a lack of analysis of uncertain factors in the process of systematic manipulation experiment, and it is difficult to make correct judgments on the advance prediction of the manipulation experiment. In order to prevent large-scale quantum gate testing, some adopt quantum circuit structure search algorithm. This algorithm depends on the structure and path of the tree-shaped super network space search space tree, depends on the weight values in different path nodes, and it is more difficult to determine the weight value under uncertain conditions. Some use quantum random walk algorithm to optimize quantum circuits. In large-scale sampling, the quantum walk method is a random walk that represents the transfer probability with probability amplitude. The probability amplitude cannot fully reflect the uncertainty, and the strategy optimization still has uncertainty. Some use the optimal quantum information manipulation method based on local manipulation. This method is positively correlated with the precision of the multi-parameter experimental platform. The instability of the quantum state is still constrained by hardware, making it very difficult to manipulate. The quantum physical system manipulates the software system, and this method is also not feasible.
[0004] The optimal strategy decision for the quantum gate experimental process, the optimization of the quantum circuit search scheme, and the determination of the optimal number of experiments for quantum information storage and manipulation are directly related to the efficiency of quantum computing fidelity during quantum information acquisition, transmission, processing and detection. In order to avoid the blindness of large-scale quantum information manipulation and quantum circuit verification under uncertain conditions, corresponding algorithms must be given.
[0005] In order to correct errors through software, transform a physical system into a quantum processor, and make intelligent decisions such as optimal strategy decisions for a type of quantum gate experimental process under uncertain conditions, optimal quantum circuit search scheme optimization, and determination of the optimal number of experiments for quantum information storage and manipulation, it is necessary to build an intelligent decision-making system for quantum information manipulation. Summary of the invention
[0006] 1. Technical issues to be solved
[0007] In view of the uncertainty of the quantum information manipulation experimental process in the prior art, the optimal strategy decision directly affects the accuracy and timeliness of quantum computing; the probability determined by a certain input statistical analysis of multiple quantum bits is uncertain, and the existing quantum circuit strategy optimization method superimposes this uncertainty; in the large-scale gate manipulation experimental space, the quantum fidelity achievement effect is constrained by the hardware and is positively correlated with the precision of the platform, and it cannot well solve how to transform a physical system into a quantum processor. The present invention provides an entropy measurement method for the optimal number of quantum gate manipulation experiments and an intelligent decision-making system. The method is used to give algorithms such as the timeliness, time-effectiveness entropy, and total time-effectiveness entropy of the quantum information manipulation process under uncertain conditions, and the algorithm is used to give an entropy measurement method for the quantum information manipulation experimental process and a method for determining the optimal number of experiments for the quantum information manipulation process, and is applied to the development of an intelligent decision-making system for optimal strategy decision of a class of quantum gate experimental processes, optimal quantum circuit search scheme optimization, and optimal number of experiments for quantum information storage manipulation, and optimizes large-scale quantum gate inspections from the software perspective, transforms a physical system into a quantum processor, and realizes the optimal strategy of the experimental process and the optimal quantum circuit search scheme. The theory and method provided by this invention are of great significance for optimizing the experimental process of quantum information manipulation, predicting the optimal number of quantum information manipulation experiments in advance, and improving the efficiency of quantum information manipulation experiments.
[0008] 2. Technical solution
[0009] The purpose of the present invention is achieved by providing the following technical solutions.
[0010] The optimal number entropy measurement method for quantum gate manipulation experiments includes:
[0011] The constraints and general rules for optimizing the quantum information manipulation process are proposed. The main contents are summarized as follows: Constraints: The constraints determined by the quantum information manipulation experimental process (hereinafter referred to as the quantum information manipulation process) are the basic principles that must be followed in constructing the quantum information manipulation process, mainly including the logical structure, experimental manipulation process and experimental method of the quantum information manipulation process. The logical structure of the quantum information manipulation process is the logical process of the manipulation experiment to complete the fidelity of quantum information (such as the quantum chip parameter calibration logic process, the superconducting quantum chip real-time automatic calibration logic process, the quantum bit gate calibration logic process, etc.), that is, the experimenter designs the system to read the quantum information system to complete a task, and the order of the test experiments performed. The experimental manipulation process structurally specifies the basic direction of the quantum information flow and is the basis for the formation of the quantum information manipulation process. The experimental manipulation method is the basic way for the experimenter to complete the collaboration and conflict resolution process in the acquisition of the experimental manipulation process. Different experimental manipulation methods produce different collaboration processes. The constraints of the collaboration process and the collaboration relationship restrict the basic direction of the quantum information flow.
[0012] General rule: The quantum information manipulation process has a strong sequential nature. Generally speaking, the preceding work in the quantum information manipulation process is the basis for the subsequent work to begin. However, the preceding work often cannot meet the requirements of the subsequent work at once. Therefore, when the preceding work cannot meet the requirements of the subsequent work, such as when objective conditions such as time or other constraints allow, the preceding work will be revised (partially revised) in accordance with the requirements of the subsequent work. This phenomenon is called a "feedback" in the quantum information manipulation experiment, and the initial node at this time is called the feedback node. Obviously, there must be "feedback" in the quantum information manipulation experiment. This is based on the fact that the quantum information manipulation process has a strong sequential nature, such as the entanglement phenomenon between quantum bits. In atomic or photon state control activities, when the preceding work cannot meet the requirements of the subsequent work, the preceding work may be partially revised in accordance with the requirements of the subsequent work, that is, "feedback".
[0013] The activity network topology structure of the quantum information manipulation process is constructed, and the main contents are summarized as follows:
[0014] For any quantum information manipulation experiment, its physical meaning can be ignored, and the quantum information manipulation experiment process can be abstracted into the operation of the system quantum information flow, and its active network topology can be constructed based on the relationship between the task flows in the system quantum information manipulation experiment. When the quantum information flow passes through the node n times, the flow is n. In this way, based on the quantum information manipulation experiment process, only the connection relationship between the nodes of the information flow and the order between the hierarchical nodes are considered, and the active network topology of the quantum information manipulation experiment process is abstracted. The optimization problem of the quantum information manipulation experiment process is transformed into the problem of optimizing the information flow of the quantum information flow through the topological structure (as shown in the attached manual). Figure 2 ).
[0015] An algorithm for determining the time entropy of quantum information manipulation process under uncertain conditions is given. The main contents are summarized as follows:
[0016] Starting from the principle of quantum information entanglement, based on the movement path of atomic or photon states and the experimental process of quantum information manipulation, "entropy" is introduced as a powerful tool for describing uncertainty states into the timeliness measurement of the experimental process of quantum information manipulation, and the "time-dependent entropy" of the topological structure is used as a powerful tool for describing uncertainty states.
[0017] In the topological structure of the quantum information manipulation process, the total flow of arcs between the nodes of the cut is called the connection degree of the cut. For example, for the i-th subprocess, the connection degree of the j-th cut is denoted as l ij . ij The calculation is determined by the shortest path of the total flow of arcs between cut nodes. The length of the direct connection is 1, and the length increases by 1 each time it is transferred.
[0018] The span number k of nodes in the topological structure graph of the quantum information manipulation process is called the connection number, which corresponds to the set of natural numbers.
[0019] In the topological structure diagram of the quantum information manipulation process, when the number of connections is k, the corresponding connection degree of the cut is l ij ,say is a topological microstate, and
[0020] In the topological structure of quantum information manipulation process, if there are i sub-processes, each sub-process is divided into j cuts, and the microscopic state is L ij , called A t is the total connection degree of the process, and
[0021] In the topological structure of quantum information manipulation process, the measure of uncertainty in the timeliness of information flow is the timeliness entropy of quantum information manipulation process, denoted as and in, is the probability of achieving the connection between nodes when the number of connections is k, the i-th subprocess, and the j-th cut:
[0022] The steps for calculating the time entropy of the control process are as follows:
[0023] Step 1: Calculate the topological structure (or active network structure) corresponding to the quantum chip parameter calibration process, and the connection degree l ij ;
[0024] Step 2: Calculate the connection number k of the nodes in the cut;
[0025] Step 3: Calculate the microscopic state L ij ;
[0026] Step 4: Calculate the total connection degree A t ;
[0027] Step 5: Calculate the time-dependent entropy
[0028] The algorithm of time efficiency value of quantum information manipulation experimental process under uncertain conditions is given, and the main contents are summarized as follows:
[0029] In a certain quantum information manipulation process, the speed at which quantum information flows during quantum information transmission is measured is called the timeliness of the quantum information manipulation process.
[0030] In the topological structure of quantum information manipulation process, the total time entropy of the ith subprocess is called and Among them, n is the number of sub-processes contained in the process; m is the number of cuts in the topological structure of the quantum information manipulation process, and k is the number of connections.
[0031] If the microscopic state of n sub-processes in the topological structure of quantum information manipulation process is A max is the maximum connection degree, and
[0032] say The maximum time-effective entropy of the topological structure of the quantum information manipulation process, and in,
[0033] The time limit of the ith subprocess of the quantum information manipulation process is called R i ,and Among them, K i (x) is a function of the number of feedbacks x of the ith subprocess of the topological structure of the quantum information manipulation process, is the time-effectiveness entropy of the ith subprocess, is the maximum time-effective entropy of the ith subprocess.
[0034] The steps for calculating the timeliness of the control process are as follows:
[0035] Step 1: Calculate the total time-dependent entropy of the topological structure of the quantum information manipulation process
[0036] Step 2: Calculate the maximum connection degree A max ;
[0037] Step 3: Calculate the maximum time-dependent entropy
[0038] Step 4: Calculate the time R i ;
[0039] Step 5: Calculate the total time RT .
[0040] The relationship between the topological feedback function and the timeliness measure is summarized as follows:
[0041] Let's record the total duration of the quantum fidelity flow as R T , define the maximum time of quantum fidelity flow corresponding to the maximum cut U as R max , the maximum flow in the network W is determined by the flow of the cut. Obviously, W is also the maximum cut, so the maximum time effect should be the same as the total time effect, that is, R max =R T .
[0042] The relationship between the optimal number of experiments and the feedback function can be summarized as follows:
[0043] The optimal number of experiments in the quantum information manipulation process can be determined by the maximum number of feedbacks in the corresponding active network topology. Assume that the active network W corresponding to the quantum information manipulation process is W. By analyzing the relationship between the feedback function of the topology structure and the time efficiency measure, it can be obtained that the maximum flow in the network is determined by the flow of the cut, and obviously W is also the maximum cut.
[0044] A table showing the relationship between the optimal number of experiments and the time efficiency measure of the active network for the quantum information manipulation process with feedback is given (Table 1). The main contents are summarized as follows:
[0045] Table 1 List of the relationships between the optimal number of experiments and time effectiveness measures
[0046]
[0047] It can be seen from Table 1 that, in the absence of feedback, the greater the total time efficiency of the quantum chip parameter calibration system, the more stable the topological structure of the quantum chip parameter calibration flow, and the higher the efficiency of the quantum information manipulation experiment.
[0048] The entropy measurement method calculates the optimal number of experiments for the control process. The steps are as follows:
[0049] Step A: Calculate the time efficiency of the topological structure sub-process of the quantum information manipulation process:
[0050]
[0051] Step B: Give the relationship between system time efficiency and feedback function:
[0052]
[0053] Step C: Give the optimal number of quantum information manipulation processes to meet the following conditions:
[0054]
[0055] Step D: Determine the number of feedback nodes in the quantum information manipulation process:

[0096] In order to make the theoretical achievements, technical routes and innovations of the present invention more clear, the theoretical achievements and technical routes of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.
[0097] First, refer to the instruction manual Figure 1 , the present invention is described in detail.
[0098] See attached Figure 1 As shown, any quantum information manipulation experiment is a quantum physical system. The manipulation of the quantum physical system by the manipulation experiment process, the quantum control ability of the software, and the calculation accuracy directly determine whether the quantum gate can achieve the characteristic of quantum state fidelity. The present invention provides the optimal entropy measurement method for quantum gate manipulation experiments to achieve prior optimization analysis. Based on the quantum information manipulation experiment process, the uncertainty of the quantum information manipulation experiment process under the complex and changeable multi-physical field coupling is analyzed, and the constraints and general rules for the optimization of the quantum information manipulation process are proposed; ignoring its physical meaning, the quantum information manipulation experiment process is abstracted into the operation of information flow, and relying on the relationship between task flows in the system quantum information manipulation experiment, only the connection relationship between each node of the information flow and the order between hierarchical nodes are considered, and the active network topology of the quantum information manipulation experiment process is abstracted, and the optimization problem of the quantum information manipulation experiment process is transformed into the problem of optimizing the information flow of quantum information flow through the topological structure.
[0099] Classify intelligent decision-making tasks, optimize the experimental process or determine the optimal number of experiments.
[0100] Starting from the principle of quantum information entanglement, based on the movement path of atomic or photon states and the experimental process of quantum information manipulation, "entropy" is introduced as a powerful tool for describing uncertain states into the measurement of the timeliness of the experimental process of quantum information manipulation. The "time-effective entropy" of the topological structure is used as a powerful tool for describing uncertain states. The concepts of system traversal of microscopic states, degree of connection, and timeliness are proposed. The time-effective entropy of the topological structure, the maximum time-effective entropy, and the time-effective algorithm are given as an algorithm for determining the timeliness of the quantum information manipulation process under uncertain conditions.
[0101] Analyze the relationship between the feedback function of the topological structure of the control experiment process and the timeliness measurement, and give the timeliness R i And the experimental feedback function K i (x) satisfies the relation
[0102] When the quantum information manipulation process has "feedback" on the i-th sub-process and needs to repeat all the activities of this process, the time limit is recorded as Feedback function K i (x) The maximum number of feedbacks meets the following conditions: In particular, when discussing a quantum information manipulation process with only one sub-process, n=1; when the quantum information manipulation process is only regarded as a cut, m=1; when any node in the quantum information manipulation process does not have a path and the span is greater than 1, k=1.
[0103] Analyze the relationship between the optimal number of experiments and the feedback function, and give the optimal number of experiments Q for system control experiments N Entropy-based measurement algorithm.
[0104] If the feedback process is only completed in a part of an activity network, the part containing the feedback process is treated as a sub-process and the algorithm is the same. i (x) The maximum number of feedback times satisfies the following formula:
[0105]
[0106] Take the maximum value of both sides:
[0107] The optimal number of experiments for quantum information fidelity under uncertainty is Q w (that is, the number of feedbacks of the active network W), obviously, for any i,

[0113] Figure 2 This is the network topology diagram of the quantum information manipulation experiment process, refer to Figure 2As shown, any quantum information manipulation experimental process can ignore its physical meaning and abstract the quantum information manipulation experimental process into a quantum information system flow activity network, and construct its activity network topology based on the relationship between task flows in the quantum information manipulation experiment. When the quantum information flow passes through the node n times, the flow is n. In this way, the quantum information manipulation experimental process is transformed into the problem of the information flow of quantum information flow through the topological structure.

[0143]
[0144] It can be obtained from Table 2 that the smaller the total time measurement value of the system, the more times the feedback is given, which indicates that the degree of order of the given "quantum chip parameter calibration process" is lower. Therefore, in the experiment of reading the quantum fidelity manipulation process, the quantum information storage error and quantum information calculation error should be minimized as much as possible, the feedback of the control process of obtaining the quantum fidelity manipulation process should be reduced, and the timeliness of the quantum chip parameter calibration system should be improved.
