QUROPE Quantum Information Processing and Communication in Europe

Making an opaque material transparent might seem like magic. But for well over a decade, physicists have been able to do just that in atomic gases using the phenomenon of electromagnetically induced transparency (EIT). Now, however, this seemingly magical effect has been observed in single atoms – and in "artificial" atoms consisting of a superconducting loop – for the first time.

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.

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.

An international team of physicists (involving physicists C. Monroe and A. Acin from the AQUTE and Q-ESSENCE projects respectively) has created the first system that can produce verifiably random numbers. The technique relies on the inherent uncertainties in quantum mechanics and future versions could help cryptographers to encode information more securely than ever before.
