Physicists have for the first time observed light drifting sideways in discrete, quantized steps, reproducing a quantum Hall effect that was previously seen only in electrons confined to ultra-thin ...

The controlled generation of single photons is an essential element of numerous quantum technology applications, such as ...

Researchers showcased a new method for generating single photons in a diamond-based quantum system. This progress brings ...

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of ...

A new quantum communication method uses the temporal Talbot effect to simplify high-dimensional quantum key distribution.

A new room-temperature quantum device developed at Stanford uses twisted light and advanced materials to link photons and ...

For more than 40 years, scientists have known that the quantum Hall effect impacts electrons in strong magnetic fields, but it turns out light also follows the fundamental phenomenon.

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.

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 ...

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 ...
