Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, ...

Werner Heisenberg's famous uncertainty principle describes one of the most intriguing features of quantum physics: certain ...

The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space ...

Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow of time and ...

The Laboratory team’s quantum “demon” uses information about a quantum system’s state and measurement results to drive similarly unusual processes, reversing the usual arrow of time in a quantum ...

An experiment with a toy universe made up of extremely cold atoms shows how time can emerge from quantum interactions, instead of existing by default ...

Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful ...

A familiar thought experiment about a hidden cat has helped scientists take a meaningful step toward building reliable ...

A surge of funding and federal action is giving the once-futuristic technology a more immediate role in everything from ...

The quantum threat is accelerating significantly. It's time to have a fresh look at the current state of affairs and what ...
