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

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

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

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

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

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 ...

At the smallest scales, heat engines can do more than Carnot ever imagined. Researchers at the University of Stuttgart have ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

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

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 ...

Physicists seem to be obsessed with cats. James Clerk Maxwell, the father of electrodynamics, studied falling feline s to investigate how they turned as they fell. Many physics teachers have used a ...
