QUANTUM STATE PREPARATION CIRCUIT GENERATION METHOD AND SUPERCONDUCTING QUANTUM CHIP

Title:

QUANTUM STATE PREPARATION CIRCUIT GENERATION METHOD AND SUPERCONDUCTING QUANTUM CHIP

Document Type and Number:

WIPO Patent Application WO/2023/010684

Kind Code:

A1

Abstract:

A quantum state preparation circuit generation method and apparatus, a superconducting quantum chip, and a storage medium. The method comprises: configuring an input register, which is composed of n quantum bits; acquiring m auxiliary quantum bits, and configuring a duplication register and a phase register, wherein the duplication register is composed of m/2 auxiliary quantum bits, and the phase register is composed of m/2 auxiliary quantum bits; processing the quantum bits by means of the input register, the duplication register and the phase register, so as to obtain a diagonal unitary matrix quantum circuit; combining the diagonal unitary matrix quantum circuit with a single-bit gate to obtain a uniform control matrix circuit; and combining different uniform control matrix circuits to obtain a quantum state preparation circuit.
