Afterpulsing studies of low noise InGaAs/InP single-photon negative feedback avalanche diodes
Boris Korzh, Tommaso Lunghi, Kateryna Kuzmenko +2
We characterize the temporal evolution of the afterpulse probability in a free-running negative feedback avalanche diode (NFAD) over an extended range, from 300 ns to 1…
Practical relativistic bit commitment
Tommaso Lunghi, Jędrzej Kaniewski, Felix Bussieres +4
Bit commitment is a fundamental cryptographic primitive in which Alice wishes to commit a secret bit to Bob. Perfectly secure bit commitment between two mistrustful parties is impo…
A self-testing quantum random number generator
Tommaso Lunghi, Jonatan Bohr Brask, Charles Ci Wen Lim +5
The generation of random numbers is a task of paramount importance in modern science. A central problem for both classical and quantum randomness generation is to estimate the entr…
Absolute calibration of fiber-coupled single-photon detector
Tommaso Lunghi, Boris Korzh, Bruno Sanguinetti +1
We show a setup for characterising the efficiency of a single-photon-detector absolutely and with a precision better of 1%. Since the setup does not rely on calibrated devices and…
