In quantum computers, information is often carried by single photons and picked up by structures named superconducting nanostrip single-photon detectors (SNSPDs). In principle, traditional type-I ...

(Nanowerk News) How can we combat data theft, which is a real issue for society? Quantum physics has the solution. Its theories make it possible to encode information (a qubit) in single particles of ...

Single photons in the mid-infrared can reveal faint galaxies or carry fragile quantum signals across space. They are valuable in astronomy, quantum communication, and even medical imaging. But ...

Chromacity Ltd reports how its tuneable ultrafast infra-red lasers are helping researchers characterise single photon detectors (SPDs), essential devices for applications including quantum key ...

Diffuse correlation spectroscopy (DCS) is used for noninvasive detection of blood flow. However, current DCS devices need to be improved to increase the signal-to-noise ratio for more accurate ...

Physicists have unveiled a new superconducting detector sensitive enough to hunt dark matter particles smaller than electrons. By capturing faint photon signals, the device pushes the search into ...
