Abstract

The invention discloses a quantum control micro-system structure, a quantum control processor and an instruction execution method, and relates to the technical field of quantum. The quantum control micro-architecture comprises a scheduler, an instruction memory, a plurality of processing units and corresponding private instruction buffers. The scheduler is used for determining k sub-circuits executed in parallel in the quantum circuit, k is an integer greater than 1, acquiring instructions corresponding to the k sub-circuits from the instruction memory, and storing the instructions in the private instruction buffers corresponding to the k processing units; wherein a target processing unit in the k processing units is used for acquiring an instruction corresponding to a target sub-circuit in the k sub-circuits from the private instruction buffer corresponding to the target processing unit and executing the instruction; and wherein the k processing units execute corresponding instructions in parallel. According to the invention, a solution of parallel sub-circuit levels is adopted, and the method has better expansion capability in the face of more complex quantum applications and continuously increasing quantum bits.

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] The quantum control microarchitecture is the specific implementation of the quantum instruction set architecture, and it is a solution to execute a given instruction set in the processor. [0003] A quantum control micro-architecture provided by related technologies 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 connected 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 ha...
