Phosphorous donors in silicon present a unique opportunity for solid-state quantum computation.(1) Electrons spins on isolated Si:P donors have very long decoherence times of ∼60 ms in isotopically purified 28Si at 7 K.(2) By contrast, electron spin dephasing times in GaAs are orders-of-magnitude shorter due spin–orbit interaction; and the background… CONTINUE READING
