CONTROL AND CANCELLATION OF SPIN BATH INDUCED DEPHASING IN SOLID-STATE ENSEMBLES

Title:

CONTROL AND CANCELLATION OF SPIN BATH INDUCED DEPHASING IN SOLID-STATE ENSEMBLES

Document Type and Number:

WIPO Patent Application WO/2018/226784

Kind Code:

A8

Abstract:

A method and system of improving T2* times for magnetic sensing using spin center ensembles is disclosed. The spin bath associated with the spin centers may be driven with a first source of electromagnetic radiation to reduce dephasing of the spin centers. The spin centers may be measured using double quantum (DQ) magnetometry in order to reduce the effects of crystal strain on T2*. Accordingly, up to an 8x improvement in DC field sensitivity may be accomplished for a spin center ensemble.
