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 ...

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 ...

Microsoft’s new quantum computer chip has a fundamental problem Microsoft’s announcement of a new quantum computing breakthrough with its Majorana 2 chip continues a trend of bold claims followed by s ...

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum ...

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

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 ...
