To push beyond this boundary, the team developed a quantum repeater system capable of creating memory–memory entanglement ...

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to ...

Keeping perfect time is far trickier than it sounds. The world’s best clocks that ...

The study shows that in quantum devices, reading a clock consumes far more energy than running it. This insight will help ...

EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist thanks to new research led by physicists at École Polytechnique Fédérale ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

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 ...
