QUANTUM COMPUTER SYSTEM AND METHOD FOR PERFORMING QUANTUM COMPUTATION WITH REDUCED CIRCUIT DEPTH

摘要

A hybrid quantum-classical computer performs a method which includes converting the output of an initial quantum circuit to a target state of a physical system. A new parametrized quantum circuit, or ansatz, is then generated with the ability to produce a state approximating the target state of the physical system. The parameters of the quantum circuit are adjusted to produce the target state, or to an approximation thereof.
