Detecting a single infrared photon is a difficult task. Whereas silicon avalanche photodiodes have become commonplace for visible light, at wavelengths beyond 1 μm, the energy of a single photon is ...

Quantum fan: the new single-photon detector comprises 32 superconducting nanowires. (Courtesy: Ryan Lannom, JPL-Caltech/NASA) A new photon detector called PEACOQ can register the arrival times of ...

A team at the National Institute of Standards and Technology in Boulder, Colorado, has reported the successful implementation of a 400,000 pixel superconducting nanowire single-photon detector (SNSPD) ...

In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, ...

About 80% of the universe's mass is thought to consist of dark matter. Yet, little is known about the composition and structure of the particles that make up dark matter, presenting physicists with ...

Researchers from the National Institute of Information and Communications Technology developed the world’s first Superconducting Wide-Strip Photon Detector (SWSPD) by inventing an innovative structure ...

There may soon be breakthroughs in the search for dark matter. A new publication in Optics Express reveals a camera consisting of superconducting nanowires capable of detecting single photons, a ...

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 ...

With a flash of light, photons simultaneously fly toward the face of a person waiting to be identified for security purposes. The packets of light bounce off the face and land on a specially ...

NASA announced it is awarding a team of researchers from Rochester Institute of Technology and Dartmouth College a grant to develop a detector capable of sensing and counting single photons that could ...

Researchers have designed a single-photon time-of-flight LiDAR system that can produce high-resolution 3D images of objects and faces that are some distance away. The top images show 3D printed ...
