When scientists repeatedly drove a strongly interacting quantum system with laser “kicks,” they expected it to heat up and ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

The pioneer of quantum computing talks about how Albert Einstein would have reacted to his experiments, the hype around the ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
