Claim 0:
1. An apparatus, comprising:
a light source configured to provide a plurality of input optical modes in squeezed states of light;
a network of interconnected reconfigurable beam splitters (RBSs) in optical communication with the light source, the network of interconnected RBSs configured to perform a unitary transformation of the plurality of input optical modes to generate a plurality of output optical modes;
an array of photon counting detectors in optical communication with the network of interconnected RBSs, the array of photon counting detectors configured to measure a number of photons in each output optical mode from the plurality of the output optical modes after the unitary transformation; and
a controller operatively coupled to the light source and the network of interconnected RBSs, the controller configured to perform at least one of tuning an angle of the unitary transformation or tuning a phase of the unitary transformation to represent an adjacency matrix of a graph, each input optical mode in the plurality of input optical modes representing a vertex of the graph.
