Problems solved by technology

[0005] In view of the problem that the existing technology cannot use the quantum instruction set on the quantum computer to realize the quantum program running on the quantum virtual machine, the present invention provides an interface system and method for unifying the quantum virtual machine and the quantum computer, which avoids the inability of the quantum program to The disadvantage of multiplexing on the quantum virtual machine and quantum computer is to realize the decoupling of software and hardware in the development of quantum programs, which is convenient for developers to use quantum virtual machines for development without quantum computers, and after the development of quantum programs is completed, they can Unmodified multiplexing to quantum computers

Abstract

The invention discloses an interface system used for unifying quantum computers and quantum virtual machines and a method, and belongs to the field of quantum computing. For the problem that the priorart cannot use quantum instruction sets on the quantum computers to realize quantum programs running on the quantum virtual machines, the method respectively provides a CPU quantum-virtual-machine interface class and a GPU quantum-virtual-machine interface class according to computing unit types, and can enable developers to select the different types of quantum virtual machines according to computing resources thereof. According to the scheme, fixed memory space of a classic computer is filled with instructions of operating the quantum computers, and an FPGA drive system can control a microwave transmitter to send corresponding waveforms according to the types of the instructions to achieve the purpose of controlling the quantum computers. The disadvantage that the quantum programs cannot be multiplexed on the quantum virtual machines and the quantum computers is avoided, operations of using the quantum virtual machines for development by the developers on the premise without a quantum computer are facilitated, and programs can be multiplexed to the quantum computers after quantum-program development is complete.

Description

technical field [0001] The invention provides a method for unifying the external interfaces of a quantum computer and a quantum virtual machine, belonging to the field of quantum computing. Background technique [0002] Quantum computers have become a key technology under research because of their ability to deal with mathematical problems more efficiently than ordinary computers, such as accelerating the time to crack RSA keys from hundreds of years to hours. However, the prototypes of quantum computers at this stage have a small number of qubits, and the actual processing speed is not as fast as that of classical computers. In order to solve this problem, people use quantum virtual machines to predict the behavior of quantum computers. This method is usually used to verify the correctness of quantum algorithms or quantum computer behaviors, and to guide the design of quantum algorithms and quantum computers. The quantum virtual machine is a simulation of the product of th...
