An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

So scientists found a workaround. Instead of building one gigantic telescope, they placed smaller telescopes far apart and combined their light. If done correctly, the system behaves like a single ...

A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions. Their study was published online on August 5, in ...

A quantum internet is only as useful as its reach, and in a first, researchers created more than a million qubit pairs across ...

Quantum entanglement has long been framed as a strange communication channel between particles, but the latest experiments suggest it can do something more concrete and practical: make light itself ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

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 ...
