1. An apparatus, comprising:
an optical circuit including at least one reconfigurable beamsplitter, the optical circuit configured to receive a plurality of input optical modes, each input optical mode from the plurality of input optical modes being in a Gaussian state from a plurality of Gaussian states, and generate a plurality of output optical modes;
at least one detector optically coupled with the optical circuit and configured to perform a non-Gaussian measurement of a first output optical mode from the plurality of output optical modes, the non-Gaussian measurement of the first output optical mode configured to cause a second output optical mode from the plurality of output optical modes to be in a first non-Gaussian state; and
a controller operatively coupled to the optical circuit and configured to change a setting of the at least one reconfigurable beamsplitter to cause the second output optical mode from the plurality of output optical modes to be in a second non-Gaussian state different from the first non-Gaussian state.
