Jamieson's group built the counted single-ion implantation capability that underpins every donor spin qubit made at UNSW and Melbourne: individual P, Sb or Bi ions are implanted into silicon through a nanoscale aperture while on-chip detector electrodes register the electron-hole pairs from each ion stop event, so the number and position of dopants is known rather than assumed. Recent directions extend this to high-atomic-number donors for nuclear-spin qudits, to colour-centre creation in diamond and silicon carbide by counted implantation, and to characterising the damage and charge environment those ions leave behind. The work is fabrication-forward but its scientific content is single-particle detection metrology. 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 contribution is upstream: the deterministic creation and validation of the very spin defects whose ensembles are later interrogated by DEER and nanoscale NMR at pT/sqrt(Hz).
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.

Kapitulnik combines cryogenic scanning-SQUID and Sagnac magneto-optic Kerr microscopy of unconventional and topological superconductors with high-precision torsion-balance experiments that test Newtonian gravity at short range and search for exotic spin-dependent forces, spanning table-top tests of fundamental physics and quantum materials characterization.
Karenowska leads the Quantum Magnonics group, which develops low-temperature microwave magnonic circuits to probe magnon physics at the quantum level. Core experiments are conducted at millikelvin temperatures in a dilution refrigerator. Research foci include: (1) propagating magnon dynamics in YIG waveguides at mK temperatures — measuring spin-wave pulse propagation and characterising the low-temperature ferromagnetic resonance frequency shift; (2) magnon-phonon (phonon-to-magnon) interconversion via magnetoelastic coupling and symmetry breaking in YIG; (3) spin-cat state generation in ferromagnetic insulators — theoretical and experimental work toward macroscopic quantum superposition states of magnons; and (4) magnon spintronics — spin-charge interconversion in YIG/metal heterostructures. These systems are relevant for microwave quantum information processing and quantum-limited magnetic-frequency-band sensing.

Kasevich is a pioneer of light-pulse atom interferometry, building cold-atom sensors of rotation, acceleration, and gravity that rival or exceed classical inertial instruments, and precision tests of general relativity and searches for dark matter and gravitational waves via large-scale atom interferometers (including MAGIS-100). His 2022 Nature paper demonstrated distributed quantum sensing with mode-entangled, spin-squeezed atomic states, extending entanglement-enhanced metrology to networks of separated sensors.
