The quantum computer is still ranking pretty high up there on the vaporware charts, somewhere between Duke Nukem Forever and a Steorn in-home power generator. Eventually we'll get there, and theoretical physicists at the University of Bristol are helping with a quantum cooling system. It is effectively a means for two qubits to cool a third, with the outer two cooled by lasers and absorbing energy from the third, which is heated to its excited state. Unsurprisingly this is all rather theoretical at this point, but the team does plan to actually such a quantum refrigerator in the not too distant future. Then, we figure, they'll host the first quantum kegger.
