Craik leads the RAVIOLIS project (SNSF Starting Grant, started July 2025) measuring atomic parity violation in barium ions at <0.1% precision. Her entanglement protocol uses multi-ion entangled states with photonic integrated waveguide addressing to common-mode-reject parity-conserving systematics. Previous work: precision measurement of Ba+ dipole transition probabilities below 1% uncertainty; first laser-guided individual addressing of Ba+ qubits with <10^-4 intensity crosstalk; isotope-shift spectroscopy in Ca+ for fifth-force searches. She is actively recruiting for postdocs and PhD students for the new Ba+ ion trap experiment.
Ballance develops techniques and technologies (including cryogenic ion traps and integrated photonic addressing chips) to control trapped atomic-ion qubits with high fidelity at scale, co-founding the spin-out company Oxford Ionics to commercialise the approach.
Berengut works on the atomic structure theory underpinning next-generation clocks: highly charged ions, whose optical transitions are both extremely narrow and exceptionally sensitive to variation of fundamental constants and to new physics, and the thorium-229 nuclear clock. He identifies which ionic species and transitions maximise sensitivity to the physics of interest while remaining experimentally accessible, and computes the many-body structure needed to interpret them — work that has directly guided the experimental HCI clock programmes at PTB, MPIK and NIST. 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 — clocks and magnetometers are the two great classes of quantum sensor; his work is on the frequency side of the same estimation problem that fixes pT/sqrt(Hz) performance on the magnetic side. Theory PI with close experimental collaborations.
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.
Fan is a junior faculty member specializing in searches for physics beyond the Standard Model through precision measurements using ion traps and molecules. Included as a borderline quantum-sensing/precision-measurement case, analogous to eEDM-style molecular and ion-trap metrology elsewhere in the department.
Haeffner's group traps and coherently controls individual and few-ion crystals to perform quantum logic spectroscopy, entanglement-enhanced metrology, and quantum simulation, using trapped ions as some of the most precisely controllable quantum sensors available. The lab is actively recruiting postdocs to work on next-generation ion-trap sensing and control techniques.
Home leads the TIQI group working with Be+ and Ca+ trapped ions. Research directions: (1) Quantum error correction — fault-tolerant gates, surface code implementations with multi-ion chains; (2) Precision metrology — ytterbium ion optical clock, mixed-species ion chain spectroscopy and ytterbium HFS measurements; (3) Macroscopic superposition and quantum contextuality — creating nonclassical motional states in harmonic oscillators for tests of quantum foundations; (4) Scalable architectures — photonic integrated waveguides for individual ion addressing, quantum logic detection of spectroscopy ions. Key publications include first two-qubit gates with mixed species and records in quantum state readout fidelity. Lab is investigating quantum logic-enhanced spectroscopy of complex atomic systems.
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.
Wolf works on trapped-ion quantum sensing, using the motional degrees of freedom of single ions and small crystals as transducers for weak electric fields and forces, together with non-classical motional states (squeezed and Fock states) to enhance the achievable sensitivity. The broader agenda is to use trapped ions as a testbed for fundamental measurement limits — quantum-enhanced amplification of small displacements, quantum non-demolition readout of motion — with an eye to applications in electric-field metrology and searches for new physics. 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 — trapped-ion motional sensing is the cleanest available platform for demonstrating the entanglement-enhanced scaling that NV ensembles at pT/sqrt(Hz) approach only in the shot-noise-limited regime. Early-career independent PI within the Quantum Control Laboratory; smaller group, higher autonomy.
