Abstract
A computer-implemented method performed by one or more computing nodes for simulating a gate operation of quantum computing is disclosed. In the method, a problem having 2size is divided into a plurality of sub-problems, each of which has 2size. A first index table for storing a first identifier is prepared for each sub-problem. In response to a request for a gate operation involving exchanges of quantum amplitudes that are designated by a target qubit at least in part, a determination is made as to whether a first condition regarding at least the target qubit and m is satisfied or not. In response to the first condition being satisfied, corresponding first identifiers in the first index table are swapped in place of the exchanges of the quantum amplitudes.
