Another day, another step bringing us closer to the next big revolution in the world of computing: replacing your transistory bits with
qubits. Researchers at Australia's Universities of New South Wales and of Melbourne, along with Finland's Aalto University, have achieved the impossibly tiny goal of reliably reading the spin of a single electron. That may not sound like much, but let's just see you do it quickly without affecting said spin. This particular implementation relies on single atoms of phosphorus embedded in silicon. Yes, silicon, meaning this type of qubit is rather more conventional than
others we've read about. Of course, proper
quantum computers depend on reading and
writing the spin of individual electrons, so as of now we effectively have quantum ROM. When will that be quantum RAM? They're still working on that bit.
Researchers develop means to reliably read an electron's spin, take us one step closer to the quantum zone originally appeared on Engadget on Thu, 30 Sep 2010 13:41:00 EDT. Please see our terms for use of feeds.
