Atatüre leads the ~30-person QOMS group at the Cavendish. Three main thrusts: (1) Spin-based quantum networks — demonstrating distant entanglement generation and photonic cluster states using semiconductor quantum dots (InGaAs, GaAs) and diamond spin defects (NV, SiV, SnV), including a many-body nuclear-spin quantum register demonstrated in 2025 (Nature Physics); (2) Quantum-enhanced nanoscale sensing — scanning NV diamond magnetometry of emergent magnetism in novel 2D/layered materials and quantum transport in nanocircuits, plus nanodiamond-based in-cell sensing (nanoMRI, thermometry, diffusion in C. elegans); (3) Novel quantum materials — hexagonal boron nitride (hBN) optically-active spin defects at room temperature, and moiré physics in TMD heterostructures. He is co-founder and CSO of Nu Quantum Ltd.

Crozier holds a joint Physics/Electrical Engineering chair and runs a nanophotonics laboratory spanning plasmonic and dielectric metasurfaces, on-chip optical trapping and manipulation of nanoparticles and cells, mid-infrared spectroscopy and detection with metasurface-enhanced and colloidal-nanocrystal devices, and light emission from 2D semiconductors. The unifying theme is engineering the local optical density of states to increase the signal available from a very small number of emitters or molecules. 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 plasmonic and dielectric antenna work is the same physics used to raise photon collection efficiency and hence the shot-noise floor of NV-ensemble magnetometers operating at pT/sqrt(Hz). Note: a substantial fraction of the group's output is device fabrication rather than sensitivity-limited measurement, which is a caveat against the stated preference.
