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

A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, ...

A team of physicists has coaxed a single, photon-like particle into behaving as if it lives in 37 different quantum ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

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

Leveraging the principles of quantum mechanics, quantum computers can perform calculations at lightning-fast speeds, enabling them to solve complex problems faster than conventional computers. In ...

Researchers have finally resolved a century-old debate over the famous "double slit" experiment, according to new research.

Alessandro Fedrizzi is in the School of Engineering & Physical Sciences, Heriot-Watt University, Edinburgh EH14 AS, UK. Read the paper: Energy–speed relationship of quantum particles challenges ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

The proposed method uses a single rare-earth ion, trapped inside a tapered optical fiber, to directly generate and guide single photons within the fiber, representing a key low-cost component for ...
