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

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 ...

Physicists at the UK’s Central Laser Facility have recorded the first observation of quantum radiation reaction, detecting how electrons lose energy in ways that classical physics cannot explain when ...

For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment ...

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 ...
