Barz builds integrated photonic quantum information processors - multi-photon entanglement, verified/blind quantum computing, and photonic networks - with direct relevance to photonic quantum metrology and distributed quantum sensing. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work contributes photonic-network and multiphoton-metrology tools.
Anthony Laing's group pioneers photonic quantum computing and quantum simulation, having invented integrated quantum photonics. Research: (1) universal reconfigurable photonic quantum processors; (2) photonic quantum simulation for chemistry and materials science; (3) photonic quantum sensing using multi-photon interference on chip. Founded PsiQuantum co-founder and Quantum in the Summer school.
Stefano Paesani works on photonic quantum information processing and quantum sensing. Research: (1) silicon quantum photonic integrated circuits for quantum computing and measurement; (2) boson sampling and quantum advantage with photons; (3) quantum sensing using photonic cluster states. Recently joined Lodahl group at NBI as associate professor.
Palomba works on nonlinear nanophotonics and plasmonics: exploiting the extreme field confinement of metallic and hybrid nanostructures to obtain efficient frequency conversion, second- and third-harmonic generation and four-wave mixing in device footprints far smaller than conventional nonlinear optics allows, and integrating these with silicon photonics. The applications the group targets include on-chip nonclassical light generation and nanoscale sensing. 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 field-enhancement physics is the same toolkit used to build the nanoantennas that raise photon collection from single NV centres and thereby move single-defect sensing toward the pT/sqrt(Hz) performance of ensembles. Borderline inclusion; the group is device-centred, which cuts against the stated preference.
Alberto Politi's Quantum nanoPhotonics Lab develops photonic quantum technology platforms for quantum information and sensing.
