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 ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, revealing light-like particles with a strikingly high-dimensional character. By ...

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 ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

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 ...
