Gangloff leads the Quantum Engineering Group at the Cavendish. Research spans three platforms: (1) Semiconductor quantum dots (InGaAs, GaAs) — demonstrating optical coherent control of quantum-dot nuclear spin ensembles (magnons, time crystals, many-body quantum registers); developing QD-based quantum repeater nodes (MEEDGARD QuantERA project); (2) Diamond group-IV spin defects (SiV, SnV, GeV) — precision positioning and high-purity single-photon generation from tin-vacancy centers; (3) Rydberg excitons in Cu₂O — exploring blockade-based optical quantum gates. The Integrated Quantum Networks Hub co-PI role underpins a broader quantum internet vision.

Morello heads the Fundamental Quantum Technologies Laboratory and is the person who first read out the spin of a single electron, and then a single nucleus, in silicon. Current directions: high-spin donors (antimony-123, with eight nuclear levels) used as qudits and as sensors of local strain and electric field; nuclear acoustic resonance, in which a strain wave rather than a magnetic field drives the nuclear spin; engineered decoherence experiments as tests of quantum foundations; and precision tomography of multi-qubit donor registers. The group's donors are among the longest-coherence solid-state spins known (seconds for nuclei). 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 — a single-donor nuclear spin in silicon is functionally an NV centre with better coherence and worse readout: the same DEER, dynamical-decoupling and nuclear-register protocols apply, and the group's high-spin qudit work is aimed at exactly the multi-level sensing enhancements that the NV community is now chasing. Preferred attribute present: sensitivity and coherence, not fabrication, are the limiting variables here.
