Popis:	While Si and Si-based materials have dominated classical electronic device technology for 50 years, quantum information processing requires very different types of devices. Silicon has also been found to be an ideal host for long-coherence quantum bits, or qubits, which are based upon the spins of electrons. The spins of electrons bound to donor impurities in isotopically enriched 28Si have been shown to have coherence times of 10 seconds or longer, at least three orders of magnitude longer than in any other solid. Considerable progress also is being made in understanding decoherence processes and extending coherence times for electrons at hetero-interfaces and in quantum dots.
