Superconducting detectors are a leading technology for the detection of single photons, but have been limited in the number of pixels that they can offer. A 400,000-pixel superconducting nanowire ...

Researchers at Purdue University have achieved a long-sought milestone, demonstrating what they call a “photonic transistor” that operates at single-photon intensities. There are few technologies more ...

The proposed method uses a single rare-earth ion, trapped inside a tapered optical fiber, to directly generate and guide single photons within the fiber, representing a key low-cost component for ...
