What we make

SNSPD (superconducting nanowire single photon detector)

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 develops the best single photon detectors, based on superconducting nanowires. The SNSPDs are provided with closed-cycle cryostat, which provides the low temperature environment for the superconducting nanowires. The high performance of our SNSPDs makes them the ideal choice for the most demanding applications.

With satisfied customers worldwide, Single Quantum is recognized for the high quality and the reliability of our detectors. We provide the best solution for your experiment and dedicated customer service.

Our photon detector features

  • Unparalleled detection efficiency
  • Low timing jitter
  • High count rate
  • Low dark counts
  • Robust fiber coupling
  • No helium consumption
  • Broadband photon detection
  • Easy to use – plug & play

The SNSPD technology

Photon detection with efficiency and time resolution

Single Quantum multi-channel SNSPD system combines high detection efficiency, high time resolution, low dark count rate, and high count rate. It can detect single photons with higher than 85% efficiency over a broad spectral range and an ultra-high timing resolution of less than 15 ps.

The detection principle is based on the transition of a nanowire from the superconductive to the resistive state upon the absorption of a single photon. The detectors are pigtailed with an optical fiber and operated in a closed-cycle cryostat at 2.5 Kelvin. The design enables continuous operation for up to 10,000 hours and requires no liquid helium consumption, thus a turn-key solution for optical measurements.

The system is designed for applications in quantum information technology, quantum communication and quantum cryptography, infrared time-resolved spectroscopy, laser ranging and remote sensing (LiDAR).

ARS cryogenics

Cryogenic solutions tailored to your experiment

Advanced Research Systems was founded in 1986 to provide cryogenic solutions for low temperature research. Today ARS is the world’s leading manufacturer of closed cycle cryocoolers and laboratory cryogenic systems. ARS is also the only major supplier of laboratory cryostats that also manufactures 4 K closed cycle cryocoolers for its use. Manufacturing their own cryocoolers allows ARS to seamlessly adapt the cryostats for challenging applications where the cryocooler must be customized for a specific application. As their partner, Single Quantum supplies ARS equipment to customers in the Netherlands and Belgium. Here you can see the portfolio of ARS cryogenic products. Contact us today to find out more.
