Team boosts metropolitan quantum teleportation to hertz rate

Quantum teleportation allows quantum information to be transferred to a remote location by using quantum entanglement and classical communication. It has been achieved with varying rates of independent photons of quantum ...

A new era for atomic clocks

A revolution is under way in timekeeping. Precision timekeeping based on atomic clocks already underpins much of our modern technology—telecommunications, computer networks and satellite-based positioning systems like GPS ...

Osram LEDs for Mini Projectors

New, particularly high-performance light-emitting diodes (LEDs) from Osram make it possible to build mini projectors. These LEDs produce enough light to project images measuring over one meter in diagonal on a wall. The small, ...

Pushing microscopy beyond standard limits

Engineers at the California Institute of Technology (Caltech) have devised a method to convert a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available ...

Silicon nanophotonics: Using light signals to transmit data

(Phys.org)—IBM announced today a major advance in the ability to use light instead of electrical signals to transmit information for future computing. The breakthrough technology – called "silicon nanophotonics" – allows ...
