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

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

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 ...

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 ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

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

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

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