Researchers realize coherent storage of light over one hour

Remote quantum distribution on the ground is limited because of the loss of photons in optical fibers. One solution for remote quantum communication lies in quantum memories: photons are stored in long-lived quantum memory ...

Laser light makes a comeback (literally)

Straight-line constant-speed propagation in free space is a basic characteristic of light. In a recent study published in Communications Physics, researchers from Osaka University discovered the phenomenon of reciprocating ...

When will your elevator arrive? Two physicists do the math

The human world is, increasingly, an urban one—and that means elevators. Hong Kong, the hometown of physicist Zhijie Feng (Boston University), adds new elevators at the rate of roughly 1500 every year...making vertical ...

'Awake' concept brings proton bunches into sync

The future of particle acceleration has begun. Awake is a promising concept for a completely new method with which particles can be accelerated even over short distances. The basis for this is a plasma wave that accelerates ...
