Quantum physics fundamentally redefines our understanding of nature by describing the behaviour of matter and energy at the smallest scales. Unlike classical theories, quantum mechanics reveals that ...

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

An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum internet. For the first time ever, the polarization state of a single photon ...

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

Researchers at Purdue University have achieved a long-sought milestone, demonstrating what they call a “photonic transistor” that operates at single-photon intensities. There are few technologies more ...

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed. When you purchase through links on our site, we ...

“We can rewind to a previous scene or skip several scenes ahead,” explained Miguel Navascués of the Austrian Academy of Sciences, of an achievement that heretofore was the province of science fiction.

Key result A six-year-long research effort has seen researchers in Canada build a chip-scale device that can generate multiphoton entangled states. (Courtesy: Ultrafast Optical Processing Group) ...
