1. A method, comprising:
estimating at least one expected output optical mode of an optical circuit based on a target output optical mode in a non-Gaussian state;
estimating a setting of the optical circuit to produce the at least one expected output optical mode;
estimating parameters of a plurality of input optical modes of the optical circuit to produce the at least one expected output optical mode, each input optical mode from the plurality of the input optical modes being in a Gaussian state from a plurality of Gaussian states;
reconfiguring (1) the optical circuit based on the setting, and (2) the plurality of input optical modes based on the parameters; and
generating (1) the at least one expected output optical mode at a first output port, and (2) the target output optical mode at a second output port of the optical circuit.
