A cluster of 7,000 sodium atoms has just been coaxed into behaving as a single, ghostly wave, stretching quantum weirdness ...

UNESCO as the International Year of Quantum Science and Technology. Recognizing 100 years since Heisenberg, Born, Jordan and ...

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

Physics pioneer Dr. Marlan Scully explores how century-old ideas are now lasers, quantum computers and detectors that can find ripples in spacetime.

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

The experiments, conducted independently by teams at the Massachusetts Institute of Technology (MIT) and the University of Science and Technology of China (USTC), used different setups to test whether ...

A near-100-year-old debate between the theoretical physicists Albert Einstein and Niels Bohr has finally been settled—and not in the former’s favor. A team of physicists in China have realized a ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University of Iowa researchers found that unwanted photons produced by lasers can be ...

A core tenet of quantum theory was imperilled this year when a team of researchers put forward a radical new interpretation of an experiment about the nature of light. At the centre of the new work ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...
