Problems solved by technology

However, quantum computers can only perform specific basic operations. Therefore, before performing quantum operations described by a unitary matrix in a quantum computer, it is necessary to decompose a general unitary matrix into unitary matrices corresponding to a series of basic operations. The decomposed matrix is ​​required It is completely (approximately) equal in function to the matrix before decomposition. This process is called (approximate) quantum compilation, but at present, quantum compilation is often performed manually, and there is a problem of low efficiency, especially not suitable for compilation with large qubits. sequence of quantum operations

Embodiment Construction

[0023] like figure 1 As shown, a method for compiling a quantum operation according to an embodiment of the present invention includes the following steps:

[0024] S1. Add a specified quantum operation layer to the initial quantum operation sequence of the father state to be opened to obtain a quantum operation sequence with undetermined parameters;

[0025] Elaborate on the "Sequence of Quantum Operations to Open the Father State":

[0026] The quantum operation sequence construction process of approximate quantum compilation can be regarded as the search process of the search space. The information stored in a state N of the search space includes: an operation sequence and its parameter values The evaluation value v of this state, the parent state N of this state parent . State N can also be written as N can be understood as a parent state to be opened, and the quantum operation sequence of the parent state to be opened is

[0027] Among them, the quantum operati...

Abstract

The present invention relates to the technical field of quantum compiling, and in particular to a compiling method, system, storage medium and electronic equipment for quantum operations. Quantum operation sequence of undetermined parameters; call the quantum operation optimizer to determine the specific value of the undetermined parameter, and obtain the quantum operation sequence with specific values; compare the quantum operation sequence with specific values ​​and the initial quantum operation sequence of the father state to be opened Whether it is approximately equivalent or not is evaluated; when the evaluation result is yes, the quantum operation sequence with specific values ​​is determined as the final compilation result, which can realize the compilation of quantum operation sequences with any number of qubits, and the efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of quantum coding, in particular to a quantum operation coding method, system, storage medium and electronic device. Background technique [0002] A quantum program, also known as a sequence of quantum operations, is specifically composed of a series of quantum operations. The unitary matrix is ​​a basic description form of quantum operations in quantum computing. However, quantum computers can only perform specific basic operations. Therefore, before performing a quantum operation described by a unitary matrix in a quantum computer, a general unitary matrix needs to be decomposed into a series of unitary matrices corresponding to basic operations, and the decomposed matrix is ​​required. It is completely (approximately) equivalent in function to the matrix before decomposition. This process is called (approximately) quantum compilation, but at present, quantum compilation is often performed manually...
