Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, ...

Quantum entanglement is often described as one of nature’s strangest secrets. Now, scientists have found it inside a crystal ...

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 in Physical ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

Quantum researchers in the twenty-first century are part of an international network that requires a great deal of interaction and communication. Around one hundred publications on the topic are ...

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 ...

Quantum entanglement—once dismissed by Albert Einstein as “spooky action at a distance”—has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...

Ronald Hanson is at QuTech and the Kavli Institute of Nanoscience, Delft University of Technology, Delft 2628 CJ, the Netherlands. The authors show that for a 10-km fibre link, entanglement between ...
