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.

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 ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction – from past to future – time could flow forward or backwards due to processes taking place at the quantum ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...

It's a well-known fact that quantum calculations are difficult, but one would think that quantum computers would facilitate the process. In most cases, this is true. Subscribe to our newsletter for ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...
