The Zhou lab at Boston College pushes the boundaries of quantum control over electron and nuclear spins in diamond to explore fundamental aspects of quantum dynamics and expand capabilities for applications. Concurrently, we utilize solid-state quantum systems as novel sensors for the electric and magnetic properties of quantum materials over a wide phase diagram. We are motivated by the overarching goal of creating electronic technologies enhanced by quantum coherence and correlation.
Controlled Quantum Dynamics
How fast? How accurate? How many? New strategies for manipulating quantum states are key to overcoming the obstacles of decoherence, error and scalability.
The atomic-scale dimensions, wide bandwidth and robust solid-state form factor of quantum defects have opened unprecedented opportunities for quantum sensing – notably, of quantum materials in the defect’s proximity.
Using an NV center on an atomic force microscope tip, magnetic fields can be imaged with nanoscale spatial resolution, potentially revealing spin and current flow patterns in materials or signaling pathways in biological systems.
