Abstract

Embodiments of the present disclosure relate to a method and device for compiling quantum circuit, equipment, and a computer readable storage medium. The method comprises: obtaining a logic instruction to be compiled for a quantum circuit, the quantum circuit comprising a plurality of qubits, the logic instruction being associated with a first qubit and a second qubit of the plurality of qubits, at least a portion of the plurality of qubits being operable using a dual-bit quantum gate; determining a path between the first qubit and the second qubit in the quantum circuit; and generating an underlying instruction for the quantum circuit corresponding to the logic instruction by adding a single-bit quantum gate based on the path.

Description

technical field [0001] Embodiments of the present disclosure relate to quantum computing, and more particularly to methods, devices, and computer-readable storage media for programming quantum circuits. Background technique [0002] At present, the topology of most superconducting quantum computers is a non-strongly connected graph structure, which limits the use of hardware, and it is difficult or impossible to achieve universal quantum computing. Universal quantum computing requires arbitrary (mutual) connections between any two qubits. In other words, given (Where U represents the space where the universal quantum task used in the computation resides, 2 n Indicates the size of the space, n is the number of qubits), can be decomposed into a single bit U 2 and a sequence of controlled NOT gates (CNOT) gates. Therefore, in addition to requiring that each qubit can perform arbitrary U 2 In addition, it is also required that any two qubits can perform the CNOT operation....
