Summary

[edit]
Description

Detection stage of the NIST prototype quantum key distribution (QKD) system: Incoming photons already have been sorted into one of two quantum states. Photons are "up-converted" from 1310 to 710 nm by one of the two NIST-designed converters at right, then sent to one of two commercial silicon avalanche photo diode units to the left.
