It feels so obvious that time moves forward that questioning it can seem almost pointless.

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

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

Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

Hoboken, N.J., July 14, 2025 — Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

By applying new methods of machine learning to quantum chemistry research, Heidelberg University scientists have made significant strides in computational chemistry. They have achieved a major ...
