A high-performance integrated single-photon detector for telecom wavelengths
Donald S. Bethune, William P. Risk, Gary W. Pabst
We have integrated a commercial avalanche photodiode (APD) and the circuitry needed to operate it as a single-photon detector (SPD) onto a single PC-board. At temperatures accessib…
Autocompensating Quantum Cryptography
Donald S. Bethune, William P. Risk
Quantum cryptographic key distribution (QKD) uses extremely faint light pulses to carry quantum information between two parties (Alice and Bob), allowing them to generate a shared,…
Enhanced Autocompensating Quantum Cryptography System
Donald S. Bethune, Martha Navarro, William P. Risk
We have improved the hardware and software of our autocompensating system for quantum key distribution by replacing bulk optical components at the end stations with fiber-optic equ…
