Single Quantum — vendor dossier

Single Quantum

Sources & detectorsEnabling supply chain
S

Dutch single-photon-detection vendor selling closed-cycle superconducting-nanowire single-photon-detector (SNSPD) systems to quantum-information, LIDAR, and deep-space-optical-communications customers. Spun out of TU Delft in 2012 by Sander Dorenbos and Val Zwiller to commercialise NbN SNSPDs developed in the Delft quantum-optics group. Flagship Eos closed-cycle multi-channel SNSPD system reports >90% system detection efficiency and <15 ps timing jitter across visible-to-telecom bands. Competes with IDQ, Photon Spot, and Quantum Opus in the multi-channel SNSPD market; roadmap targets larger pixel counts and detector arrays for imaging applications.
