Gigahertz quantum key distribution with InGaAs avalanche photodiodes
Z. L. Yuan, A. R. Dixon, J. F. Dynes, A. W. Sharpe, and A. J. Shields
We report a demonstration of quantum key distribution (QKD) at gigahertz clock rates with InGaAs avalanche photodiodes (APDs) operating in a self-differencing mode. Such a mode of operation allows detection of extremely weak avalanches so that the detector afterpulse noise is sufficiently suppressed ... [Appl. Phys. Lett. 92, 201104 (2008)] published Mon May 19, 2008.
