ID281 Superconducting Nanowire

Single-photon detector with 85% quantum efficiency and fastest electronics

  • Best-in-class quantum efficiency: >85%
  • High detection rate: >20 MHz
  • Jitter: <30 ps (FWHM)
  • Low dark count rate: <10 Hz

IDQ’s ID281 series detection system consists of a superconducting nanowire detector (SNSPD) combined with high-performance electronics and a reliable cryogenic system. The system operates at 0.8 K and offers impressive performance: 85% quantum efficiency, count rate >20 MHz, dark counts <10 Hz, jitter <30 ps (FWHM) and no afterpulsing.

The complete system is plug and play and includes: cryocooler, stable and adjustable bias current sources, cryogenic amplification stage, discriminators and counters. It comes with the best-in-class control and timing electronics: 1 GHz counters, 8 ps time resolution and fast processing rate (100 Mevents/s).

Our superconducting nanowire single-photon detectors (SNSPD) can also be integrated into your own cryogenic system: the ID281 comes with everything that is necessary to install it in your own cryostat; including electronics, software, feed-throughs, cryogenic cables and connectors.
