Atomically-thin Single-photon Sources for Quantum Communication [PDF]
npj 2D Materials and Applications, 2022 To date, quantum communication widely relies on attenuated lasers for secret key generation. In future quantum networks, fundamental limitations resulting from their probabilistic photon distribution must be overcome by using deterministic quantum light ...

Quantum communication, reference frames and gauge theory [PDF]
Phys.Rev. A73 (2006) 042306, 2006 We consider quantum communication in the case that the communicating parties not only do not share a reference frame but use imperfect quantum communication channels, in that each channel applies some fixed but unknown unitary rotation to each qubit.

Semi-quantum communication: Protocols for key agreement, controlled secure direct communication and dialogue [PDF]
Quantum Inf. Process. 16, 295 (2017), 2017 Semi-quantum protocols that allow some of the users to remain classical are proposed for a large class of problems associated with secure communication and secure multiparty computation. Specifically, first time semi-quantum protocols are proposed for key agreement, controlled deterministic secure communication and dialogue, and it is shown that the ...
