In the last conference of the JSAP (12p-N103-6), I proposed a simulation method of photonic quantum computation, especially continuous variable (CV) photonic quantum computation, using tensor networks. Additionally I proposed Gaussian Boson Sampling (GBS) as a simulation target. GBS is known to be able to solve graph problems using the output probability distributions.
In this talk, we will discuss the results of simulations using the proposed method on GBS, which encodes the real problem of counting the number of perfect matchings in a graph.
