Very simplified toy models help scientists get started, but the real world is far more complex.

Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a ...

“Our system is remarkable because it’s incredibly simple,” said paper author and physicist David Grier of New York University ...

A time crystal, a long-life quantum system approaching perpetual motion, has been hooked up to its environment for the first time, unlocking an intriguing way to increase quantum computational and ...

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

Quantum computers can compare molecules that are much larger than the ones classical computers can compute, Accenture said on its website. “The big hope is that a quantum computer can simulate any ...
