Ajoy's group uses NV and P1 centers in diamond to hyperpolarize nuclear spins via optically pumped dynamic nuclear polarization, dramatically boosting NMR/MRI signal for chemical sensing and nanoscale spectroscopy. This builds directly on the broader lineage of NV-ensemble quantum sensing experiments (DEER, nanoscale NMR, T1 relaxometry) that have reached pT/sqrt(Hz)-class sensitivities, extending it toward practical hyperpolarized-sensing applications; the lab is actively recruiting postdocs.
Pioneer in nanocrystal science. Sensing-relevant directions: (1) coherent Er spin defects in colloidal nanocrystal hosts as scalable solid-state spin qubit platform (2024 paper with Awschalom); (2) size- and shape-controlled nanocrystal synthesis for mid-IR sensing applications; (3) fundamental scaling laws governing optical properties for sensor design.

Anders designs integrated-circuit quantum and magnetic-resonance sensors: EPR-on-a-chip (single-chip ESR spectrometers reaching ~1e9 spins/sqrt(Hz)), chip-scale NMR relaxometry for point-of-care, and CMOS/SiGe-integrated diamond NV magnetometers - miniaturizing spin sensing onto silicon. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is the integrated-circuit route to deployable NV/EPR ensemble sensing.

PREFERRED. Cappellaro pioneered quantum magnetic sensing with electronic spin defects (NV centers) in diamond, and her group designs and controls solid-state spin qubit systems for quantum sensing, simulation, and quantum information processing, combining theoretical insight into spin dynamics with experimental control of dynamical decoupling and nuclear-spin registers for nanoscale NMR. This builds on the broader lineage of NV ensemble quantum sensing (DEER, NMR, T1 relaxometry) that has pushed AC/DC magnetic sensitivities toward the pT/sqrt(Hz) regime, which her group's Hamiltonian-engineering and nuclear-spin-register approaches aim to extend further.
Choi builds large-scale, individually addressable arrays of solid-state spin qubits (NV centers and related defects) and entangles ancilla nuclear/electronic spins to demonstrate high-precision, entanglement-enhanced quantum sensing, extending the ensemble NV magnetometry regime (DEER/T1 protocols at pT/βHz) toward single- and few-spin sensors with quantum-error-corrected readout.
PREFERRED. Choi is a theorist working at the intersection of quantum information science and out-of-equilibrium many-body dynamics, and with experimental collaborators (Lukin group) he developed quantum-logic-enhanced protocols that let dense, interacting NV ensembles surpass the interaction-limited sensitivity bound for AC magnetometry. This directly extends the lineage of NV ensemble quantum sensing experiments (DEER, nanoscale NMR, T1 relaxometry) that have driven ensemble magnetometers toward pT/sqrt(Hz) sensitivities, by using engineered many-body Hamiltonians and quantum control rather than dilution alone.
Develops quantum sensors based on neutral atoms and solid-state atom-like defects (e.g. NV diamond) for measuring inertial forces, magnetic fields, and time, and applies nanophotonics/nanofabrication to improve the size, weight, and performance of quantum sensing instruments; collaborates with Mikhail Kats on metasurface-enhanced atomic magnetometers.
The de Leon lab engineers nitrogen-vacancy and other color centers in diamond and wide-bandgap materials as solid-state quantum sensors and qubits, spanning materials growth and surface chemistry, nanophotonic integration, and magnetic-field/thermal sensing of quantum materials, alongside a parallel effort on superconducting qubit noise and loss. This builds on the broader tradition of ensemble NV magnetometry (DEER, NMR, T1 relaxometry) that has reached pT/sqrt(Hz)-class sensitivities, which de Leon's group extends toward single- and few-spin scanning-probe magnetometry of correlated electron materials.
