Fast Single Photon Detectors and real-time Key Distillation: Enabling High Secret Key Rate QKD Systems
Fadri Grünenfelder, Alberto Boaron, Matthieu Perrenoud +11
Quantum Key Distribution has made continuous progress over the last 20 years and is now commercially available. However, the secret key rates (SKR) are still limited to a few Mbps.…
Advantages of gated silicon single photon detectors
T. Lunghi, E. Pomarico, C. Barreiro +3
We present a gated silicon single photon detector based on a commercially available avalanche photodiode. Our detector achieves a photon detection efficiency of 45\pm5% at 808 nm w…
Free Running Single Photon Detection based on a negative feedback InGaAs APD
Tommaso Lunghi, Claudio Barreiro, Olivier Guinnard +4
InGaAs/InP-based semiconductor avalanche photodiode are usually employed for single-photon counting at telecom wavelength. However they are affected by afterpulsing which limits th…
2.23 GHz gating InGaAs/InP single-photon avalanche diode for quantum key distribution
Jun Zhang, Patrick Eraerds, Nino Walenta +3
We implement an InGaAs/InP single-photon avalanche diode (SPAD) for single-photon detection with the fastest gating frequency reported so far, of 2.23 GHz, which approaches the lim…
Practical fast gate rate InGaAs/InP single-photon avalanche photodiodes
Jun Zhang, Rob Thew, Claudio Barreiro +1
We present a practical and easy-to-implement method for high-speed near infrared single-photon detection based on InGaAs/InP single-photon avalanche photodiodes (SPADs), combining…
High speed coherent one-way quantum key distribution prototype
Damien Stucki, Claudio Barreiro, Sylvain Fasel +8
We report the first real world implementation of a Quantum Key Distribution (QKD) system over a 43dB-loss transmission line in the Swisscom fibre optic network. The QKD system is c…
