Researchers Create Silicon-Based Quantum Bit

angry tapir writes "Researchers at the University of New South Wales in Australia have created the world's first working quantum bit based on a single atom in silicon. The research team was able to both read and write information using the spin, or magnetic orientation, of an electron bound to a single phosphorous atom embedded in a silicon chip. In February, UNSW researchers revealed they had successfully created a single-atom transistor using a single phosphorous atom in a silicon crystal."

Re:Bit not a Qubit

They show relatively clear Rabi oscillations, which are a definite proof of the quantumness of the evolution of their system (which has nothing to do with entanglement). So, yes, this is a genuine qubit, albeit not a perfect one.
