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 ...

Quantum mechanics is extremely successful at describing the behavior of matter at the atomic level. This success forces one to accept that certain aspects of physical reality go far beyond our ...

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, ...

Quantum teleportation has moved from science fiction into laboratory reality, but not in the way popular culture imagines. Instead of beaming people or objects across space, physicists are learning ...
