Abstract: Provided herein are various techniques and equipment for establishing secure non-classical communications between distant nodes. In one example, a method includes introducing, by at least one photon source, source photons into corresponding waveguides configured to convert the source photons into randomly timed pairs of resultant non-classical photons having corresponding polarization states. The method also includes providing first photons of each of the pairs for measurement of the corresponding polarization states and timing, and providing second photons of each of the pairs for combination into a beam for transfer to a distant node and establishment of a cryptographic key, where the second photons from one of the waveguides is presented in an orthogonal polarization before combination.

Abstract: A system for superadditivity for remote sensing and communication includes coupling optics to direct several input pulses received over a communication channel to an interaction medium. A probe beam entering the interaction medium at an angle performs state preparation and manipulation. A detector reads the output light of the interaction medium. Orthogonality states of symbols represented by the plurality of input pulses are affected by the communication channel, and the interaction medium provides the output light via local entanglement of the plurality of input pulses and the probe beam.

Abstract: Information can be transmitted through classical and quantum communication channels in parallel and at rates that enhance secure communication. The quantum communication is scaled to a transmission rate of 10 GHz or more, which matches the rate of classical communication transmission. During transmission of information (e.g., a message) through a classical channel, a quantum channel can transmit quantum key information used to construct a new key (e.g., a new decryption key) from the prior key. As a result, the same key is not reused for decryption and can be discarded after use. Further, a multiplexing system can encode and transmit both classical and quantum communication at the GHz-level transmission rate as a single optical beam, while a demultiplexing can receive and decode the information from the single optical beam.
