Distributed Quantum Computing Simulation Method and Apparatus

A distributed quantum computing simulation apparatus, comprising a main process node and a plurality of sub-process nodes, wherein:

• the main process node is configured to convert a quantum circuit to be simulated into a tensor network that is represented by an undirected graph, and segment the undirected graph into a plurality of sub-graphs by using a genetic algorithm that is based on operation resources of a distributed system;
• the plurality of sub-process nodes are configured to respectively perform tensor contraction and merging on the plurality of sub-graphs for connected tensors until only one tensor is left, so as to finally obtain zero-order tensors of the plurality of sub-graphs at the same time;
• and
• the main process node is further configured to acquire and superpose the zero-order tensors of the plurality of sub-graphs at the same time, so as to determine a zero-order tensor of the undirected graph, and use the zero-order tensor of the undirected graph as a probability amplitude of a positive operator value measurement element, so as to perform quantum computing simulation.
