Winpenny holds the Regius Chair in Chemistry at Manchester and is a world leader in molecular magnetism and molecular nanomagnets for quantum technologies. Research directions: (1) Molecular nanomagnets — synthesis of Cr7Ni 'horseshoe' rings and related cage clusters as prototype molecular qubits with long T2 times; (2) Multi-qubit molecular architectures — covalently linked molecular qubit pairs and arrays for quantum gate operations and distributed sensing; (3) Quantum error correction in molecules — designing molecular systems encoding logical qubits with error protection; (4) Quantum sensing applications — molecular spin systems as ultra-sensitive nanoscale magnetic sensors in the sub-nm regime. Leading the NPL M4Q Network and UK molecular qubit community.
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.
Yang works on the systems-level physics of silicon spin qubits: operating qubits at elevated temperatures (above one kelvin, where cryo-CMOS control electronics can be co-integrated), valley and spin-orbit engineering, and the electrical control of spin qubits without micromagnets. The 'hot qubit' programme in particular is an engineering argument about where the classical/quantum boundary should sit in a real machine. 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 — raising the operating temperature of a spin sensor while preserving coherence is the same trade a pT/sqrt(Hz) NV ensemble makes implicitly by working at room temperature; Yang's work is the silicon community's attempt to buy back some of that convenience. Borderline inclusion — this is quantum computing rather than sensing — retained under the inclusive rubric.
Andrew Young's group develops solid-state quantum photonic systems, focusing on deterministic single photon emitters and spin-photon interfaces. Research: (1) quantum dot and colour-centre emitters coupled to cavities and waveguides for near-unity efficiency; (2) spin-photon interfaces for quantum repeaters; (3) cavity quantum electrodynamics for quantum networking.
