Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how fast it happens.

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

A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is. Featuring new ...

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

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

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

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

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to ...

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 ...
