Researchers at the University of Warsaw have unveiled a breakthrough method for detecting and precisely calibrating terahertz ...

Photon blockade is a quintessential phenomenon in quantum optics, wherein a strongly nonlinear system prevents the absorption of additional photons once a single photon is present, effectively ...

Using single photons as qubits has become a prominent strategy in quantum information technology. Accurately determining the number of photons is crucial in various quantum systems, including quantum ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

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).

Lighten up, people: a fascinating new paper has dropped that describes the shape of a single photon, the smallest possible form of energy in an electromagnetic field that we commonly know as light.

Large quantum optical networks of tryptophan in protein architectures – the kinds found in mammalian brains, but also in all eukaryotes and even in some bacteria – influence their collective response ...

Recent progress in both analog and digital quantum simulations heralds a future in which quantum computers could simulate — and thereby illuminate — physical phenomena that are far too complex for ...

A team of researchers from the National Institute of Standards and Technology in Boulder, Colorado, has successfully developed a super-sensitive camera capable of detecting a single photon. This ...
