Einstein called it “spooky action at a distance,” but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that ...

The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a mystery—and physicists are deeply divided about what is actually going on, a ...

For centuries, the concept of consciousness has intrigued philosophers and scientists alike. Often deemed too abstract for scientific exploration, consciousness has been largely left to philosophical ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

If you asked a thousand physicists, they would all disagree. This statement could apply to any number of topics – whether the universe is infinite, what dark matter is made of, how to make wires ...

An international team of researchers has identified a quantum counterpart to Bayes’ rule. The likelihood you assign to an event is influenced by what you already believe about the surrounding ...
