Department(s)/lab(s): Chemistry | Ajoy Lab @ UCB
Summary:

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.

Department(s)/lab(s): Physics | Quantum Engineering Group (Cappellaro Lab) @ MIT
Summary:

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.

Department(s)/lab(s): Electrical Engineering | Choi Lab @ Stanford
Summary:

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/√Hz) toward single- and few-spin sensors with quantum-error-corrected readout.

Department(s)/lab(s): Electrical Engineering and Computer Science | Quantum Photonics Laboratory (Englund Lab) @ MIT
Summary:

PREFERRED. Englund's Quantum Photonics Laboratory builds solid-state quantum technologies spanning diamond NV-center ensembles, integrated photonic circuits, and single-photon detectors, including a CMOS-integrated NV-ensemble quantum sensor for vector magnetometry and 4-pi steradian field sensing, and cavity-QED schemes for nuclear-spin readout aimed at nanoscale/inertial sensing. This continues the trajectory of NV ensemble quantum sensing (DEER, chip-scale NMR, T1 relaxometry) toward pT/sqrt(Hz)-class, chip-integrated magnetometers, alongside quantum networking and photonic quantum computing work.

Department(s)/lab(s): QuTech / Applied Sciences | Taminiau Lab — NV Centers and Spin Quantum Networks (QuTech) @ TU Delft
Summary:

Tim Taminiau (QuTech team leader, Assoc Prof) develops NV-center quantum registers for sensing and quantum networks. Research: (1) NV-center nuclear spin registers — quantum control of up to 50 coupled 13C nuclear spins; (2) nanoscale NMR sensing — mapping external spin networks with sub-nm resolution; (3) silicon-carbide spin qubits — VSi centres for scalable quantum networks with fast entanglement rates; (4) quantum error correction in multi-spin diamond registers.
