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.
