Biercuk's Quantum Control Laboratory sits precisely at the intersection of control engineering and precision measurement. The group uses trapped ytterbium ions — including large 2D Penning-trap crystals — as both quantum simulators and as calibrated sensors, and is best known for noise spectroscopy: using the qubit itself as a spectrum analyser of its environment, then designing dynamical-decoupling and open-loop control sequences that null the dominant noise. That programme produced Q-CTRL, his quantum control software company, and more recently a serious push into quantum sensing for navigation (magnetic anomaly navigation, quantum-enhanced RF sensing) as a commercial and defence application. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — his filter-function and noise-spectroscopy formalism is now standard equipment in the NV community for designing the DEER and dynamical-decoupling sequences that deliver pT/sqrt(Hz) sensitivity; a candidate from that background would find the theoretical toolkit immediately familiar. Large, well-funded group with strong industry pathways.

Develops quantum sensing platforms at the biology interface. Core NV-center work: (1) widefield NV magnetic imaging of action potentials in neurons and cardiac tissue; (2) NV-based single-molecule NMR at 14 T resolving molecular structure with single-molecule sensitivity; (3) charge-sensitive shallow NV nanoprobes monitoring real-time cellular electrophysiology; (4) biocompatible diamond surface functionalization enabling multiplexed DNA microarray biosensing; (5) fluorescent-protein spin qubits as biological alternatives to diamond NV (2025 paper, Physics World Top-10 Breakthrough). Runs full NV stack: hot implantation, widefield and confocal ODMR, T1/T2/Hahn echo/DEER/Rabi, automated fitting pipelines. 2026 Sloan Fellow. PhD Lukin/Harvard; postdoc Chu/Stanford. Argonne joint appointment.

Tan trained at NIST Boulder in the Wineland lineage and brought quantum-logic spectroscopy and entanglement-enhanced metrology to Sydney. His independent programme builds trapped-ion systems for quantum simulation of vibronic and chemical dynamics, for bosonic/qudit encodings, and — most relevant here — for precision measurement that exploits entangled states to beat the standard quantum limit. The group also works on high-fidelity gates and on using motional modes as sensitive transducers of weak forces and electric fields. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — entanglement-enhanced protocols are the natural next step beyond the shot-noise-limited pT/sqrt(Hz) ensemble measurements that define the current NV state of the art, and Tan is one of a small number of Australian PIs actually implementing them. Mid-career, actively building; a strong option for a candidate wanting to move from spin ensembles to entangled sensors.
