Coherent State Quantum Key Distribution Without Random Basis Switching
Christian Weedbrook, Andrew M. Lance, Warwick P. Bowen +3
The random switching of measurement bases is commonly assumed to be a necessary step of quantum key distribution protocols. In this paper we show that switching is not required for…
Quantum Passwords
Mile Gu, Christian Weedbrook
A quantum password is a quantum mechanical analogue of the classical password. Our proposal is completely quantum mechanical in nature, i.e. at no point is information stored and m…
No-Switching Quantum Key Distribution using Broadband Modulated Coherent Light
Andrew M. Lance, Thomas Symul, Vikram Sharma +3
We realize an end-to-end no-switching quantum key distribution protocol using continuous-wave coherent light. We encode weak broadband Gaussian modulations onto the amplitude and p…
