Researchers Create Silicon-Based Quantum Bit 46
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."

I'm of the opinion adding more qubits to a superposition is going to be an exponentially hard problem.
History tells otherwise. [quantenblog.net]
