Claim 0:
1. A quantum noise process analysis method, applicable to a computer device, the method comprising:
performing quantum process tomography (QPT) on a quantum noise process of a target quantum system, to obtain dynamical maps of the quantum noise process wherein the QPT involves at least one measurement of the target quantum system;
extracting transfer tensor maps (TTMs) of the quantum noise process from the dynamical maps, the TTMs being used for representing a dynamical evolution of the quantum noise process; and
analyzing the quantum noise process according to the TTMs by:
extracting a second-order memory kernel of the quantum noise process according to the TTMs when the quantum noise process is a steady noise;
calculating a correlation function of the quantum noise process according to the second-order memory kernel of the quantum noise process; and
performing a Fourier transform on the correlation function of the quantum noise process to obtain a frequency spectrum of the quantum noise process.
