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

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

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

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 ...

The concept of time has troubled philosophers and physicists for thousands of years, and the advent of quantum mechanics has not simplified the ...

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 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 ...

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 ...

Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has ...
