Member: Single Quantum

Light detectors are crucial components of optical imaging and telecommunication systems. The ultimate photon detector is capable of detecting even an elementary particle of light, a single photon.

Single Quantum was established in 2012 as the first European company manufacturing and commercializing the ground-breaking technology of superconducting single photon detectors.

Our multi-channel detection system has already been chosen by more than 160 academic and industrial labs all over the world to perform complex optical measurements. The unique combination of unparalleled detection efficiency and time resolution makes our superconducting detectors the ideal choice for quantum communication and cryptography, infrared fluorescence spectroscopy, and laser ranging.

Our mission is to make the world’s fastest and most sensitive light sensors limited only by the law of physics.


• Two-photon quantum interference
• Photon antibunching
• Laser ranging for environment monitoring
