Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

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, ...

Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has ...

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 ...

Space rarely gives up its secrets easily. For instance, what looks like a single ...

Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is ...

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 ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...
