Abstract
The spin of an electron or a nucleus in a semiconductor1 naturally implements the unit of quantum information-the qubit. In addition, because semiconductors are currently used in the electronics industry, developing qubits in semiconductors would be a promising route to realize scalable quantum information devices2. The solid-state environment, however, may provide deleterious interactions between the qubit and the nuclear spins of surrounding atoms3, or charge and spin fluctuations arising from defects in oxides and interfaces4. For materials such as silicon, enrichment of the spin-zero 28Si isotope drastically reduces spin-bath decoherence5. Experiments on bulk spin ensembles in 28Si cryst..
