Photon-efficient quantum key distribution using time–energy entanglement with high-dimensional encoding by Tian Zhong, Hongchao Zhou, Robert D Horansky, Catherine Lee, Varun B Verma, Adriana E Lita, Alessandro Restelli, Joshua C Bienfang, Richard P Mirin, Thomas Gerrits, Sae Woo Nam, Francesco Marsili, Matthew D Shaw, Zheshen Zhang, Ligong Wang, Dirk Englund, Gregory W Wornell, Jeffrey H Shapiro, Franco N C Wong

“…Under photon-starved conditions the rate of detection events is much lower than the photon generation rate, because of losses in long distance propagation and the relatively long recovery times of available single-photon detectors. Multi-bit encoding in the photon arrival times can be beneficial in such photon-starved situations. …”

Afterpulsing and instability in superconducting nanowire avalanche photodetectors by Marsili, Francesco, Najafi, Faraz, Molnar, Richard J., Berggren, Karl K.

“…We studied the dependence of the reset time of SNAPs on the device inductance and discovered that SNAPs can provide a speed-up relative to superconducting nanowire single-photon detectors with the same area but with some limitations: (1) Reducing the series inductance of SNAPs (necessary for the avalanche formation) could result in the detectors operating in an unstable regime, (2) a trade-off exists between maximizing the bias current margin and minimizing the reset time of SNAPs, and (3) reducing the reset time of SNAPs below ∼1 ns resulted in afterpulsing.…”
