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

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

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

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 ...

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

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

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

Scientists have long known that light can sometimes appear to exit a material before entering it -- an effect dismissed as an illusion caused by how waves are distorted by matter. Now, researchers at ...

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