NETWORK ANALYSIS USING OPTICAL QUANTUM COMPUTING

原文（中文）

There is described a method of detecting an anomaly in a transaction network using an optical quantum-computing device. The method comprises obtaining transaction information. generating a transaction graph based on the transaction information. encoding inputs of a Gaussian Boson Sampling (GBS) device based on the transaction graph. processing outputs of the GBS device to identify one or more dense subgraphs of the transaction graph. and generating a detection output identifying one or more of the identified dense subgraphs as representative of a potential anomaly. There is also described an apparatus for detecting an anomaly. comprising a GBS device having a photon source. a linear optical interferometer and a photon detector. and a computer device configured to program inputs of the GBS device.
