Quantum control microarchitecture, quantum control processor and instruction execution method

Abstract

The application discloses a quantum control micro-architecture, a quantum control processor and an instruction execution method, and relates to the field of quantum technology. The quantum control micro-architecture includes: a scheduler, an instruction memory, a plurality of processing units and corresponding private instruction buffers. The scheduler is used to determine the k sub-circuits executed in parallel in the quantum circuit, where k is an integer greater than 1, obtain the instructions corresponding to the k sub-circuits from the instruction memory, and store them in the private instruction buffers corresponding to the k processing units respectively. The target processing unit in the k processing units is used to obtain instructions corresponding to the target sub-circuits in the k sub-circuits from its corresponding private instruction buffer for execution; wherein, the k processing units execute their corresponding instructions in parallel. The present application adopts a sub-circuit level parallel solution, which has better scalability in the face of more complex quantum applications and increasing qubits.

Description

technical field [0001] The embodiments of the present application relate to the field of quantum technology, and in particular, to a quantum control micro-architecture, a quantum control processor, and an instruction execution method. Background technique [0002] A quantum control microarchitecture is a specific implementation of a quantum instruction set architecture, a solution for executing a given instruction set in a processor. [0003] A quantum control micro-architecture provided by the related art uses a distributed architecture, that is, the compiler will generate its corresponding instructions for each qubit separately, and the control module corresponding to each qubit will be merged with the docking analog channel. as a separate hardware submodule. When the system is running, a complete quantum program needs to be converted into multiple independent instruction files corresponding to different qubits, and then executed by the corresponding hardware sub-modules....
