Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers aren’t so sure.

Two recent studies published in Nature and Science Advances explored quantum approaches that could improve the precision of ...

The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency ...

For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask ...

Physicists have uncovered how direct atom-atom interactions can amplify superradiance, the collective burst of light from ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions. (Nanowerk News) A team of theoretical ...

IBM’s new 120-qubit experiment marks a leap forward, advancing technology that could one day crack Bitcoin’s encryption.

Bitcoin’s quantum reckoning may still be years away, but the fear has already arrived. Breakthroughs from Google, Caltech, ...
