Quantum Computation

Combing makes for neat qubits

Summary: 

Frequency comb entangles two atomic qubits

Physicists in the US (including AQUTE physicist C. Monroe) have used an optical "frequency comb" to reliably entangle a pair of atomic qubits. The breakthrough bodes well for practicable quantum computing because it allows for simpler manipulation of quantum states than in previous systems.

BEC coupled to mechanical oscillator

Summary: 

Ultracold gas offers new way of probing tiny vibrations

Physicists in Germany and France (including AQUTE members Theodor W. Hänsch, Jakob Reichel, and Philipp Treutlein) have coupled a Bose–Einstein condensate (BEC) of ultracold atoms to the vibrations of a mechanical oscillator for the first time.
