Protecting The Spin Coherence of Silicon Vacancy Color Centers from Thermal Noise Using Diamond MEMS

Not Accessible

Your library or personal account may give you access

Abstract

Spin coherence time, T2*, of the silicon vacancy color center in diamond is limited by thermal phonons existing in the lattice. We show how this process can be engineered by applying static strain using a micro-electro-mechanical system (MEMS) fabricated on diamond. By suppressing the relevant thermal process, we demonstrate the improvement of spin T2*.
