Coincidence Correlation and Counting

A key method for single photon based quantum technologies

 

Photon coincidence detection, coincidence correlation and coincidence counting are fundamental methods in optical quantum technologies. Typical examples are Hanbury-Brown-Twiss setups to study single photon sources, quantum communication and quantum key distribution (QKD), the study of entanglement using Hong-Ou Mandel (HOM) setups,
Bell state measurements, or experiments on quantum gates towards the development of quantum computers.
Time-tagging devices from PicoQuant are ideal for such applications, as they record absolute signal arrival times on several detection channels in parallel.
