A new superconducting camera with 400,000 pixels can capture the universe’s dimmest lights. The camera is so sensitive that it can photograph a single photon. It’s the highest resolution camera of its type. 

The camera was developed by scientists at the National Institute of Standards and Technology (NIST). It has 400 times more pixels than any other device of its kind. The camera can be used to: 

• Capture faint light signals from space 
• Explore details within the human brain 
• Advance astronomy and quantum computing 
• Capture astronomical images under extremely low-light conditions 
• Advance biomedical imaging 

The camera was developed by NIST researchers Adam McCaughan and Bakhrom Oripov, along with collaborators from NASA’s Jet Propulsion Laboratory and the University of Colorado Boulder. They integrated signals from several pixels onto a few room-temperature readout wires

NIST stands for the National Institute of Standards and Technology. It’s a non-regulatory government agency that’s part of the U.S. Department of Commerce. NIST was founded in 1901 and is headquartered in Gaithersburg, Maryland. 

NIST’s mission is to promote American innovation and industrial competitiveness. It develops, promotes, and maintains metrics and standards for several industries. NIST also supports and develops measurement standards for specific services or products. 

NIST’s work includes: 

• The NIST Cybersecurity Framework, which helps businesses of all sizes understand, manage, and reduce their cybersecurity risk 
• Research on superconducting components used to build neuromorphic circuits 
• Research on a new quantum ruler to explore exotic matter

Unlike traditional cameras that rely on semiconductor-based sensors to capture a broad spectrum of light, superconductive cameras can detect single photons, making them extremely efficient for capturing faint light sources, such as distant stars or galaxies

The magic happens when these cameras are cooled to nearly absolute zero. At this temperature, electrical currents flow without resistance, a phenomenon known as‘superconductivity’. But when a photon — a particle of light — hits the camera’s detector, it disrupts this flow at a particular pixel. By mapping out these disruptions across the camera’s grid, scientists can form an image.

The NIST camera is made up of grids of ultrathin electrical wires, cooled to near absolute zero, in which current moves with no resistance until a wire is struck by a photon. In these superconducting nanowire cameras, the energy imparted by even a single photon can be detected because it shuts down the superconductivity at a particular location (pixel) on the grid. Combining all the locations and intensities of all the photons makes up an image
