A new type of single photon detector called the thermally-coupled imager (TCI) has been developed by NIST. This device uses superconducting nanowire single photon detectors (SNSPDs), which are known for their high performance in detecting single photons with speed and accuracy. The TCI improves on existing technology by allowing the efficient readout of thousands of detectors using just a single readout line, making it easier to track both the time and location of each detected photon over a large area.
This advancement has important applications in fields like quantum computing, space communications, and astronomy. The TCI can operate across a wide range of wavelengths, making it versatile for different uses. The technology represents a significant step forward in the development of efficient and scalable photon detection systems for quantum and optical technologies.
