Physicists have coaxed particles of light into undergoing opposite transformations simultaneously, like a human turning into a werewolf as the werewolf turns into a human. In carefully engineered ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

Input/output is the term for time before and after a particular physical moment or scenario, and in certain quantum scenarios, those ‘befores’ and ‘afters’ can be interchangeable. Researchers have ...

Observing the flow of time at the quantum scale reveals a puzzling energy phenomenon: the energy required to simply read the time astronomically exceeds that consumed by the device's operation itself.

Quantum effects are no longer confined to ultra-cold chips and vacuum chambers. For the first time, researchers have ...

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

YORKTOWN HEIGHTS, N.Y. - OCTOBER 18: Exhibition model of IBM Q System One quantum computer. (Photo by Misha Friedman/Getty Images) Like the hapless tramps in Samuel Beckett’s play Waiting for Godot, ...

If you’re waiting for an “ah-ha” moment, sorry, pal, not today. Nevertheless, there are some exciting things cooking up in quantum computing, which can solve complex problems exponentially faster than ...
