Quantum bit mapping method, apparatus, and computer device

Abstract

The application relates to a quantum bit mapping method, comprising the following steps: acquiring a coupling relationship among a plurality of quantum bits in a quantum chip; dividing a quantum circuit of the quantum chip to obtain a plurality of sub-circuits arranged in sequence; determining a first sub-circuit set and a second sub-circuit set corresponding to the quantum circuit; a second sub-circuit group of the second sub-circuit set contains at least two adjacent first sub-circuit groups of the first sub-circuit set, and each first sub-circuit group contains at least one sub-circuit; determining a first quantum bit mapping result and a second quantum bit mapping result of a line segment to which each second sub-circuit group belongs based on the coupling relationship; determining a first target quantum bit mapping result with a smaller number of bit gates from the first quantum bit mapping result and the second quantum bit mapping result; and sequentially splicing the first target quantum bit mapping results of the line segments according to the arrangement order of the line segments in the quantum circuit to obtain a quantum bit mapping result of the quantum circuit.
