Over the past decade, researchers have become good at creating devices that emit single ...

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1920, Danish physicist Niels Bohr proposed that although light (photons) has a dual nature, behaving as both particle and wave, ...

In 1927, Albert Einstein and Neils Bohr debated the nature of what’s known as complementarity—the idea that a photon’s dual wave-like and particle natures can’t be measured at the same time. Now, two ...

An international collaboration of researchers, led by Philip Walther at University of Vienna, have achieved a significant breakthrough in quantum technology, with the successful demonstration of ...

The DOE's Argonne National Laboratory has launched its Activated Materials Lab to study radiation effects in nuclear reactor ...

The 7th international workshop on new Photon-Detectors took place from 3 to 5 December 2025 at Bologna’s Palazzo d’Accursio.

Two-photon microscopy is a type of fluorescence microscopy that, rather than exciting the sample with a single photon, makes use of multiple photons. The advantage over more traditional one-photon ...
