Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

Scientists have used a first-of-its-kind technique to visualize two entangled light particles in real time — making them appear as a stunning quantum "yin-yang" symbol. The new method, called biphoton ...

Scientists have introduced a groundbreaking form of quantum entanglement known as frequency-domain photon number-path entanglement. This leap in quantum physics involves an innovative tool called a ...

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

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 ...

Duality ellipse The amount of coherence is linked to the amount of waveness and particleness of a quantum system through an duality ellipse relation. The coherence, modulated by the object shape, can ...

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...
