Dlaczego informatycy (niektórzy) studiują mechanikę kwantową a fizycy zainteresowali się szyfrowaniem ? Od maszyn liczących do komputerów Cambridge Centre for Quantum Computation Tranzystory w technologii 25 nm Od kwantowego procesu do kwantowego elementu CHCl 3 John Preskill http://www.theory.caltech.edu/people/preskill/ Spin is In At IBM they ought to know What makes a fast computer go. They seem to think electron spin Is something worth investing in. Today's computers, by and large, Rely upon electron charge. But we might speed them up a lot With spins inside a quantum dot. We'd like to put a qubit there And tickle it with extra care. Alas, it isn't very clear How fast the spin will decohere. Today we'll hear from Dave DiVince. In '96, and ever since He's been for spin in his preprints. Let's see if you will be convinced.
