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…
Concise Security Bounds for Practical Decoy-State Quantum Key Distribution
Charles Ci Wen Lim, Marcos Curty, Nino Walenta +2
Due to its ability to tolerate high channel loss, decoy-state quantum key distribution (QKD) has been one of the main focuses within the QKD community. Notably, several experimenta…
Intrinsically stable light source at telecom wavelengths
Fernando Monteiro, Thiago Guerreiro, Bruno Sanguinetti +1
We present a highly stable light source at telecom wavelengths, based on a short erbium doped fiber. The high stability arises from the high inversion of the Er3+ion population. Th…
Quantum Metropolitan Optical Network based on Wavelength Division Multiplexing
Alex Ciurana, Jesus Martinez-Mateo, Momtchil Peev +4
Quantum Key Distribution (QKD) is maturing quickly. However, the current approaches to its application in optical networks make it an expensive technology. QKD networks deployed to…
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…
