Light controls two-atom quantum computation

Some powerful rulers of the world may dream of the possibility to get in touch with their colleagues on different continents unnoticed by friends or foes. Someday, new quantum technologies could allow for making these wishes ...

Researchers make breakthrough in the quantum control of light

Researchers at UC Santa Barbara have recently demonstrated a breakthrough in the quantum control of photons, the energy quanta of light. This is a significant result in quantum computation, and could eventually have implications ...

Einstein's dream surpassed

(PhysOrg.com) -- A constant stabilization experiment of a quantum state has been successfully carried out for the first time by a team from the Laboratoire Kastler Brossel headed by Serge Haroche. The researchers succeeded ...

Seeing a photon without absorbing it

Light is of fundamental importance. It allows us to see the world around us and record pictures of our environment. It enables communication over long distances through optical fibers. All current methods of detecting light ...

A quantum pump without a crank

Pumps, in a nutshell, are devices that use cyclic motion to attain the steady transport of some cargo. In a bicycle pump, the repeated up and down strokes of a piston create air flow. In a Archimedean screw pump, water is ...
