Quantum cnot Gate Implemented
From about a week ago, here is a main stream news story, but the original story appears in Nature, which unfortunately is not free.
Seems like a pretty big milestone, would be nice to know the specifics. From the abstract: "In our experiment, two 40Ca+ ions are held in a linear Paul trap and are individually addressed using focused laser beams; the qubits are represented by superpositions of two long-lived electronic states."
Just how long is "long-lived"?
