Methods and systems for communicating over a quantum channel

摘要: Alice generates a sequence of key bits forming an initial cryptographic key. then uses the and cipher to control respective parameters quantum encoding process applied pulses, where used is known Bob. releases encoded pulses towards Bob over channel. previously agreed-upon parameter, such as basis, detection received from Alice, thus producing outcome for each pulse. derives final outcomes. Because select bases by both are parties, method allows be distributed with full basis alignment compared 50% BB84, allowing efficient distribution multiple hops.
