Hamilton heads the Quantum Electronic Devices group and is Deputy Director of the ARC Centre for Future Low Energy Electronics (FLEET). The group works on hole-based quantum devices in GaAs and germanium, where strong spin-orbit coupling allows all-electrical spin control, and on topological materials and one-dimensional transport. The measurements are millikelvin transport and noise spectroscopy of very small signals in mesoscopic devices. 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 — the link is indirect — this is charge/spin transport rather than magnetometry — but the group's expertise in low-noise cryogenic measurement and in spin-orbit-mediated electrical spin control is directly transferable to electrically-detected spin sensing, which is the main alternative to the optical readout that limits pT/sqrt(Hz) NV ensembles. Borderline inclusion; kept under the inclusive rubric.

PREFERRED. Ji is launching the Ji Quantum Lab at MIT to build next-generation scanning-probe and on-chip quantum sensors (millimeter-wave impedance microscopy, 'RFlexiScope') that map nanoscale conductivity, magnetism and collective excitations in strongly correlated and topological quantum materials down to the quantum limit. The lab is explicitly recruiting PhD students, postdocs, and UROPs as of its founding.
