Free-running InGaAs single photon detector with 1 dark count per second at 10% efficiency
Boris Korzh, Nino Walenta, Tommaso Lunghi +2
We present a free-running single photon detector for telecom wavelengths based on a negative feedback avalanche photodiode (NFAD). A dark count rate as low as 1 cps was obtained at…
A fast and versatile QKD system with hardware key distillation and wavelength multiplexing
Nino Walenta, Andreas Burg, Dario Caselunghe +17
We present a 625 MHz clocked coherent one-way quantum key distribution (QKD) system which continuously distributes secret keys over an optical fibre link. To support high secret ke…
Experimental bit commitment based on quantum communication and special relativity
T. Lunghi, J. Kaniewski, F. Bussieres +6
Bit commitment is a fundamental cryptographic primitive in which Bob wishes to commit a secret bit to Alice. Perfectly secure bit commitment has been proven impossible through asyn…
