The Quantum Optics and Spectroscopy Group at the University of Innsbruck in Austria has created an entanglement of eight quantum particles, yielding a quantum byte or "qubyte", or eight qubits. This is an important step toward the realization of a practical quantum computer, which would use superposed quantum states to perform complex calculations. A writeup of this work is available in English and German. The formal paper will appear in the December 1st edition of Nature.
