Interesting papers in experimental ion trap quantum computation:
Creation of a six-atom ‘Schrödinger cat’ state from Wineland’s group at NIST Boulder, Nature 438, 639-642 (1 December 2005.) Schrodinger’s cat is now six qubits big! And growing! What a cute little kitten.
Scalable multiparticle entanglement of trapped ions from Blatt’s group in Innsbruck. Nature 438, 643-646 (1 December 2005.) In this paper the group discusses experiment they performed which created the so-called “W” entangled state for up to eight qubits. That’s a quantum byte, peoples! Amazingly the group performs full state tomography on these states. Wow that sounds like an awful lot of graduate student hours.
