Two separate groups demonstrate the temporary storage and subsequent release of photons using very different quantum devices.

Light stored in a Bose-Einstein condensate can be manipulated with light to create an optical AND gate.

Individual neutral atoms trapped in optical tweezers have been cooled to their quantum ground state, raising hopes that they can be used to process quantum information.

David Wineland and Serge Haroche, who studied photons and atoms in new ways, have won the 2012 Nobel Prize in Physics.

Two separate experiments have demonstrated the fast transport of trapped ions using trapping potentials that trace out the path for the ions to follow.

A link in a quantum network is built from a hybrid atomic system, connected by fiber optics.

Vibrations of the atoms in a molecule are used to implement a Fourier transform orders of magnitude faster than possible with devices based on conventional electronics.

An NMR-based quantum computer can simulate a hydrogen molecule and accurately yield its ground-state energy.

The demonstration of entanglement between two neutral atoms would be a key step toward using them for quantum computation.

Ion traps can store quantum information with long coherence times and support universal quantum computations.

Loading cold atoms into a hollow-core optical fiber enables all-optical switching with just several hundred photons.

A specially prepared Bose-Einstein condensate would produce oppositely directed beams of entangled atoms, which could be used for investigations of entanglement and quantum information theory. In the past only beams of entangled photons have been produced.
