SPECTRAL DECOMPOSITION OF COMPOSITE SOLID STATE SPIN ENVIRONMENTS THROUGH QUANTUM CONTROL OF SPIN IMPURITIES

摘要

Methods and systems are described for spectral decomposition of composite solid-state spin environments through quantum control of electronic spin impurities. A sequence of spin-control modulation pulses are applied to the electronic spin impurities in the solid-state spin systems. The spectral content of the spin bath that surrounds the electronic spin impurities within the solid-state spin system is extracted, by measuring the coherent evolution and associated decoherence of the spin impurities as a function of number of the applied modulation pulses, and the time-spacing between the pulses. Using these methods, fundamental properties of the spin environment such as the correlation times and the coupling strengths for both electronic and nuclear spins in the spin bath, can be determined.
