Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could ...

Entanglement observed in near-macroscopic objects

Perhaps the strangest prediction of quantum theory is entanglement, a phenomenon whereby two distant objects become intertwined in a manner that defies both classical physics and a common-sense understanding of reality. In ...

Next step towards quantum network based on micromechanical beams

In recent years, nanofabricated mechanical oscillators have emerged as a promising platform for quantum information applications. Quantum entanglement of engineered optomechanical resonators would offer a compelling route ...

Quantum physicists achieve entanglement record

Entanglement is of central importance for the new quantum technologies of the 21st century. A German-Austrian research team is now presenting the largest entangled quantum register of individually controllable systems to ...

Entangled LED first to operate in the telecom window

Researchers have demonstrated the first quantum light-emitting diode (LED) that emits single photons and entangled photon pairs with a wavelength of around 1550 nm, which lies within the standard telecommunications window. ...
