What we make

Superconducting nanowire single photon detector

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

Single Quantum makes the world’s fastest and most sensitive light sensors limited only by the laws of physics, with a technology based on superconducting nanowire single photon detector (SNSPD).

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

The SNSPD technology

Photon detection with efficiency and time resolution

The Single Quantum multi-channel SNSPD system combines high detection efficiency, high time resolution, low dark count rate, and a high count rate. It can detect single photons with higher than 90% 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. This makes it 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, imaging, laser ranging, and remote sensing (LiDAR).
