Superconducting Nanowire Single Photon Detector

SNSPD is a type of single photon detector that operates based on the superconducting properties of thin nanowires. When a single photon interacts with the superconducting nanowire, it disrupts the superconductivity, leading to a measurable electrical signal. SNSPDs are highly sensitive, capable of detecting individual photons with high efficiency and low noise.

The advantages of SNSPDs in PHOTEC company lie in their superior performance characteristics, which make them ideal for 

various applications such as quantum communication, quantum computing, lidar, satellite ranging, and other advanced photonics applications.

PHOTEC leverages their SNSPDs to provide cutting-edge solutions to our customers and drive innovation in the field of quantum technology.
