In a paper entitled: "Solid-state quantum memory using the 31P nuclear spin", published in the October 23, 2008 issue of the journal Nature,[7] a team of scientists from the U.K. and U.S. reported the first relatively long (1.75 seconds) and coherent transfer of a superposition state in an electron spin "processing" qubit to a nuclear spin "memory" qubit. This event can be considered the first relatively consistent quantum data storage, a vital step towards the development of quantum computing. Recently, a modification of similar systems (using charged rather than neutral donors) has dramatically extended this time, to 3 hours at very low temperatures and 39 minutes at room temperature.[8] Room temperature preparation of a Qbit based on electron spins instead of nuclear spin was also demonstrated by a team of scientist from Switzerland and Australia.[9]
