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

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, ...

A research team in China has built a quantum dot device that produces photon pairs with record-setting purity, achieving a two-photon fraction of 0.983(1). The work, published in Nature Materials, ...

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

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 ...

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

It's time for the latest update in confirming things we already knew—and, as always, it's being far more interesting than you might expect. Simply put, scientists have conducted a super-advanced ...

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 ...
