At Last, Single-Photon Cameras Could Peer into Your Brain (spectrum.ieee.org)

A 0.4-megapixel single-photon camera based on superconducting nanowires has been created.
Single photon cameras measure light with unsurpassed sensitivity and speed.
Cameras can be used to capture space, measure illumination in photonic quantum computers and communications.
Superconducting nanowires can capture each photon and operate at different frequencies.
Increasing the size of cameras opens up possibilities for applications in biomedical imaging.
Near infrared light is ideal for penetrating human tissue.
Silicon-based detectors are not suitable for these frequencies.
The team is working with bioimaging teams to tailor the device to their needs.

Superconductor-based cameras that can detect a single photon—the smallest smidgeon of light—have existed for 20 years, but they’ve remained confined to laboratories due to the inability to scale them past a few pixels. Now, a team at the National Institute of Standards and Technology (NIST) in Boulder, Colo., has created a 0.4-megapixel single-photon camera—400 times as large as the previous biggest camera of its type.
