Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Human bodies are not entirely dark. A growing body of research suggests that every living person emits an ultra‑faint glow, a ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

A team of physicists has coaxed a single, photon-like particle into behaving as if it lives in 37 different quantum ...

Controlled generation of single-photon emitters in silicon (red) by broad-beam implantation of ions (blue) through a lithographically defined mask (left) and by a scanned focused ion beam (right).
