Design And Research Of Quantum Computer Interface Framework

Quantum computers use quantum superposition and quantum entanglement to achieve parallel computing with ultra-fast computing power,which is 100 million times faster than current computers,The design of the quantum computer interface becomes the key to the application of quantum computers.In this paper,on the basis of introducing the basic knowledge of quantum mechanics,qubits and superconducting qubits,We explored the basic programming methods of quantum processing devices,designed a conversion scheme between quantum processors and computer CPUs,and used EDA tools to simulate this design.The results show that this scheme can achieve the data transmission capability of quantum processor and CPU well,and can fulfill the tasks of quantum computing and CPU control system.On the basis of introducing the basic knowledge of quantum mechanics,we have studied the core components of superconducting quantum computers,the characteristics and basic principles of the three basic superconducting qubits formed by superconducting Josephson structures,and the advantages and disadvantages of the three superconducting qubits are compared.and several methods are designed based on them.A superconducting quantum processor made up of superconducting qubits details the working principles of quantum processors,the implementation of qubits,the coupling between qubits,and the reading of qubits,and gives mathematical derivation..On the basis of quantum processors,a high-speed parallel computing capability of quantum computers is adopted,and classical computer processors are used to process the data of quantum computer processors.This paper proposes a quantum computer interface architecture design scheme.The CPU and quantum QPU are connected together,and the classic CPU completes the control part of the system,while the quantum QPU performs the quantum computation.This scheme greatly reduces the design complexity of the quantum computer and has the advantages of superior performance and simple implementation.Then,we explored the method of local programming in the quantum computer interface architecture.The binary signal is converted into an analog signal using a digital-to-analog converter,and then it is substituted into a quantum processor through a quantum coupling device for quantum computation.In this method,it can be generalized to couple any number of quantum processors to two or any number of digital-to-analog converters,and to locally program the quantum processor through a demultiplexer circuit.Finally,The simulation of the scheme is carried out through Quartus II?Modelsim and Matlab.First,designed the quantum computing process,analyzed the advantages and disadvantages of several data channels,and finally chose the appropriate string parallel structure as a data path.Comparing the quantum computer with the classical computer solution time,and given the timing diagram,because the quantum computer and classical computer processing transmission speed does not match,we add asynchronous FIFO in the interface to cache,to ensure that the data can be transmitted correctly.Finally,the performance of the QPU and CPU interface of the quantum processor is analyzed.The simulation diagram is given from the data recognition probability and the dynamic power consumption respectively.The simulation results and analysis show that the QPU and CPU interface architecture of the quantum processor is in a certain degree.Frequency and temperature conditions have higher data processing accuracy and lower energy consumption.
