Giessen works on ultrafast nano-optics and plasmonics, plasmonic and metasurface sensors, femtosecond two-photon 3D-printed micro-optics (on fiber tips and detectors), widely tunable ultrafast/mid-IR sources for molecular sensing, and Rydberg-exciton quantum optics in cuprous oxide. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work sits adjacent as a nanophotonic sensing and light-source enabler.
Goldys was Deputy Director of the ARC Centre of Excellence for Nanoscale BioPhotonics and now leads a nanoscale biophotonics group in Biomedical Engineering. The programme is about extracting diagnostic information from very weak optical signals inside cells and tissue: luminescent and upconverting nanoparticle probes with long lifetimes that allow time-gated, background-free detection; hyperspectral unmixing of native cellular autofluorescence (NADH, FAD, porphyrins) as a completely label-free readout of cell state, which she has pushed toward clinical use in reproductive medicine and cancer; and nanoparticle-mediated therapy. 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 — time-gated luminescence and NV relaxometry are two solutions to the same problem — how to read a faint, specific signal out of an autofluorescent, optically hostile biological background — and her clinical translation experience is exactly the missing capability in most quantum-biosensing groups. Preferred attribute present: advanced/label-based imaging with a genuine human-application pathway.

Herkommer holds the chair for Design and Simulation of Optical Systems at Stuttgart's Institute of Applied Optics (ITO), the group behind much of the optical-design side of two-photon-3D-printed micro-optics -- printing complete multi-lens objectives on the tip of a single-mode fibre, which enables ultrathin endoscopic imaging and micro-objectives that cannot be made by conventional polishing. Related work covers freeform and metasurface optics, aberration theory, and adaptive/computational imaging. Long-running collaboration with Giessen (existing PI) at the 4th Institute of Physics. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), a borderline inclusion on the microscopy axis: the group does not do sensing itself, but it makes the optics that get a diffraction-limited spot into places you otherwise cannot reach -- directly useful for fibre-coupled NV probes and endoscopic quantum sensing.
Studies optical quantum science in solid-state systems with emphasis on photonic integration. Directions: (1) photonic integration of NV-center spin qubits in diamond nanophotonic circuits for scalable quantum sensing arrays; (2) 2D semiconductor (TMD) nanophotonic devices exploiting valley and spin-valley degrees of freedom; (3) engineering light-matter interactions for quantum information and sensing in nanoscale optical cavities. Key goal: scalable on-chip quantum sensing platforms.
Hutchison works on molecular polaritonics: what happens to chemistry when molecular electronic or vibrational transitions are strongly coupled to a confined optical mode in a Fabry-Perot or plasmonic nanocavity. He was among the first to show that vibrational strong coupling modifies ground-state chemical reactivity, and the group continues to probe polariton-modified energy transfer, photochemistry and transport, alongside single-molecule spectroscopy and 2D-material photonics. 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 connection to quantum sensing is the cavity: the same Purcell and collective-coupling physics that concentrates optical density of states around a molecule is what is used to improve photon collection and readout fidelity in NV ensembles operating at pT/sqrt(Hz). This is fundamental light-matter physics with a clear nonclassical-state angle.
Imamoglu leads the Quantum Photonics Group at ETH, working at the intersection of quantum optics and condensed matter physics. Research directions: (1) Quantum emitters in 2D semiconductors — TMD monolayers (MoSe2, WSe2) host localized excitons that act as single-photon emitters; electrically tunable quantum dots in TMD heterostructures with high purity and spin-photon entanglement; developing them as quantum sensors of local electronic correlations at nanometer scales; (2) Strongly correlated electron physics — Mott insulator / Wigner crystal phases in moiré TMD bilayers probed optically with single-photon resolution; mapping electronic phases with nanometer spatial resolution; (3) Polariton quantum fluids — exciton-polaritons in 2D semiconductor microcavities; (4) Quantum nonlinear optics — photon-photon interactions via giant Kerr nonlinearities in strongly coupled quantum dots. Quantum sensing angle: quantum emitters as nanoscale probes of correlated phases.
