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 ...

Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to ...

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

The true danger isn't just that quantum computers will read our emails. It's that they'll fundamentally change what's possible in the material world.
