1. A method, comprising:
calculating a plurality of permuted matrices of an initial matrix that characterizes a linear transformation of a plurality of input states;
determining a plurality of settings of an optical circuit based on the plurality of permuted matrices, each setting in the plurality of settings associated with an electric power, from a plurality of electric powers, consumed by the optical circuit;
determining a selected setting of the optical circuit based on the electric power from the plurality of electric powers and consumed by the optical circuit at each setting from the plurality of settings associated with the electric power; and
sending one or more control signals to a plurality of reconfigurable circuit portions of the optical circuit to implement the selected setting on the optical circuit.
