摘要:
A solid state electronic spin system contains electronic spins disposed within a solid state lattice and coupled to an electronic spin bath and a nuclear spin bath, where the electronic spin bath composed of electronic spin impurities and the nuclear spin bath composed of nuclear spin impurities. The concentration of nuclear spin impurities in the nuclear spin bath is controlled to a value chosen so as to allow the nuclear spin impurities to effect a suppression of spin fluctuations and spin decoherence caused by the electronic spin bath. Sensing devices such as magnetic field detectors can exploit such a spin bath suppression effect, by applying optical radiation to the electronic spins for initialization and readout, and applying RF pulses to dynamically decouple the electronic spins from the electronic spin bath and the nuclear spin bath.
