Sensing with Diamond NV Centers: the Double-edged Sword of Sensitivity (QTu4A.1)
Presenter: Ania Bleszynski Jayich, University of California Santa Barbara


Solid state spin qubits, in particular the nitrogen vacancy (NV) center in diamond, offer a path towards truly nanoscale imaging of condensed matter and biological systems with sensitivity to single nuclear spins. Here I discuss our NV-based magnetic imaging experiments as applied to condensed matter systems, where we have imaged current flow patterns in graphene as well as skyrmions, nanoscale spin textures. A grand challenge to improving the spatial resolution and magnetic sensitivity of the NV is mitigating surface-induced quantum decoherence, which I will discuss in the second part of this talk. Decoherence at interfaces is a universal problem that affects many quantum technologies, but the microscopic origins are as yet unclear. Our studies guide the ongoing development of quantum control and materials control, pushing towards the ultimate goal of NV-based single nuclear spin imaging.

Phononic Quantum Networks of Spins in Diamond (QTu4A.2)
Presenter: Hailin Wang, University of Oregon

The design and experimental implementation of a phononic quantum network of spins in diamond, which can overcome the inherent scalability problem of conventional mechanical quantum networks, will be discussed.
