1306.5940 (Boris Korzh et al.)

A high-speed multi-protocol quantum key distribution transmitter based
on a dual-drive modulator

Boris Korzh, Nino Walenta, Raphael Houlmann, Hugo Zbinden
We propose a novel source based on a dual-drive modulator that is adaptable and allows Alice to choose between various practical quantum key distribution (QKD) protocols depending on what receiver she is communicating with. Experimental results show that the proposed transmitter is suitable for implementation of the Bennett and Brassard 1984 (BB84), coherent one-way (COW) and differential phase shift (DPS) protocols with stable and low quantum bit error rate. This could become a useful component in network QKD, where multi-protocol capability is highly desirable.
