METHOD FOR GENERATING QUANTUM STATE PREPARATION CIRCUIT, QUANTUM STATE PREPARATION METHOD, AND QUANTUM DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18199474 titled 'METHOD FOR GENERATING QUANTUM STATE PREPARATION CIRCUIT, QUANTUM STATE PREPARATION METHOD, AND QUANTUM DEVICE

Simplified Explanation

The present disclosure describes a method for generating a quantum state preparation circuit, a quantum state preparation method, and a quantum device.

  • The method involves configuring an input register and determining the number of auxiliary quantum bits for the quantum state preparation circuit.
  • A copy register and a target register are configured based on the number of auxiliary quantum bits.
  • A diagonal unitary matrix quantum circuit is obtained by constructing a circuit using the input register, copy register, and target register, following a quantum bit copy mode obtained from a grid restriction condition.
  • The diagonal unitary matrix quantum circuit is combined with a single bit quantum gate to obtain at least one uniformly controlled gate circuit.
  • The quantum state preparation circuit is generated based on the at least one uniformly controlled gate circuit.


Original Abstract Submitted

The present disclosure relates to a method for generating a quantum state preparation circuit, a quantum state preparation method, and a quantum device. The method includes: configuring, based on parameters of the quantum state preparation circuit, an input register for the quantum state preparation circuit and determining a number of auxiliary quantum bits; configuring a copy register and a target register according to the number of the auxiliary quantum bits; obtaining a diagonal unitary matrix quantum circuit by performing circuit construction through the input register, the copy register and the target register according to a quantum bit copy mode obtained based on a grid restriction condition; combining the diagonal unitary matrix quantum circuit and a single bit quantum gate to obtain at least one uniformly controlled gate circuit; and generating the quantum state preparation circuit based on the at least one uniformly controlled gate circuit.
