Gigahertz decoy quantum key distribution with 1 Mbit/s secure key rate
A. R. Dixon, Z. L. Yuan, J. F. Dynes +2
We report the first gigahertz clocked decoy-protocol quantum key distribution (QKD). Record key rates have been achieved thanks to the use of self-differencing InGaAs avalanche pho…
A High Speed, Post-Processing Free, Quantum Random Number Generator
J. F. Dynes, Z. L. Yuan, A. W. Sharpe +1
A quantum random number generator (QRNG) based on gated single photon detection of an InGaAs photodiode at GHz frequency is demonstrated. Owing to the extremely long coherence time…
An avalanche-photodiode-based photon-number-resolving detector
B. E. Kardynal, Z. L. Yuan, A. J. Shields
Avalanche photodiodes are widely used as practical detectors of single photons.1 Although conventional devices respond to one or more photons, they cannot resolve the number in the…
Gigahertz quantum key distribution with InGaAs avalanche photodiodes
Z. L. Yuan, A. R. Dixon, J. F. Dynes +2
We report a demonstration of quantum key distribution (QKD) at GHz clock rates with InGaAs avalanche photodiodes (APDs) operating in a self-differencing mode. Such a mode of operat…
Biphoton interference with a quantum dot entangled light source
R. M. Stevenson, A. J. Hudson, R. J. Young +4
We demonstrate optical interferometry beyond the limits imposed by the photon wavelength using 'triggered' entangled photon pairs from a semiconductor quantum dot. Interference fri…
Quantum key distribution using a triggered quantum dot source emitting near 1.3 microns
P. M. Intallura, M. B. Ward, O. Z. Karimov +5
We report the distribution of a cryptographic key, secure from photon number splitting attacks, over 35 km of optical fiber using single photons from an InAs quantum dot emitting ~…
