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

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 ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

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 ...

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

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 ...

Quantum technologies are systems that can compute data, sense their surrounding environment or perform other functions leveraging quantum mechanical effects. Connecting these technologies over long ...
