  • Control and cancellation of spin bath induced dephasing in solid-state ensembles
    Patent number: 11156674
    Abstract: A method and system of measuring a direct current magnetic field using a plurality of spin centers are disclosed. A 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 spin dephasing times. An electromagnetic response of at least one of the plurality of spin centers may be observed using an electromagnetic radiation collection device. Accordingly, up to an eight times improvement in DC field sensitivity may be accomplished for a spin center ensemble.

  • ORDER OF MAGNITUDE IMPROVEMENT IN T*2 VIA CONTROL AND CANCELLATION OF SPIN BATH INDUCED DEPHASING IN SOLID-STATE ENSEMBLES
    Publication number: 20210080517
    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 8× improvement in DC field sensitivity may be accomplished for a spin center ensemble.
