Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

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

To most of us, time feels as solid as the phone alarm that drags us out of bed or the calendar that fills up faster than we ...

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

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...

Scientists have found “strange quarks” that originated as virtual particles that sprang from nothing Quantum physics paints a ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

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

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...
