Simulation Method in Quantum Control, Classical Computer, and Storage Medium

A classic computer, comprising:

• at least one processor;
• and
• a memory communicatively connected to the at least one processor, wherein
• the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to:
• acquire a hardware parameter corresponding to a quantum system and a target quantum gate required to be realized by the quantum system;
• acquire a pulse function represented on the basis of discrete time slices, wherein pulse parameter values within a time period from start time to end time of a time slice are the same;
• determine target step sizes corresponding to the discrete time slices in the pulse function, to obtain pulse parameter values within time durations corresponding to the target step sizes according to the target step sizes corresponding to the time slices and the pulse function;
• and
• obtain simulation quantum gates within the time durations corresponding to the target step sizes on the basis of obtained pulse parameter values within the time durations corresponding to the target step sizes and the hardware parameter of the quantum system, until obtaining a target simulation quantum gate within a preset pulse time duration, wherein a difference between the target simulation quantum gate within the preset pulse time duration and the target quantum gate meets a preset rule.

A non-transitory computer-readable storage medium storing computer instructions, wherein the computer instructions, when executed by a computer, cause the computer to:

• acquire a hardware parameter corresponding to a quantum system and a target quantum gate required to be realized by the quantum system;
• acquire a pulse function represented on the basis of discrete time slices, wherein pulse parameter values within a time period from start time to end time of a time slice are the same;
• determine target step sizes corresponding to the discrete time slices in the pulse function, to obtain pulse parameter values within time durations corresponding to the target step sizes according to the target step sizes corresponding to the time slices and the pulse function;
• and
• obtain simulation quantum gates within the time durations corresponding to the target step sizes on the basis of obtained pulse parameter values within the time durations corresponding to the target step sizes and the hardware parameter of the quantum system, until obtaining a target simulation quantum gate within a preset pulse time duration, wherein a difference between the target simulation quantum gate within the preset pulse time duration and the target quantum gate meets a preset rule.
