1. A system comprising:
a coupling optics configured to direct a plurality of input pulses received over a communication channel to an interaction medium;
a probe beam entering the interaction medium at an angle and configured to perform state preparation and manipulation; and
a detector configured to readout output light of the interaction medium,
wherein orthogonality states of symbols represented by the plurality of input pulses are affected by the communication channel, and
the interaction medium is configured to provide output light via local entanglement of the plurality of input pulses and the probe beam.
