Krishna Balram (inaugural lecture May 2026) develops photonic quantum engineering at the intersection of photonics, mechanics, and quantum information. Research: (1) piezoelectric optomechanical resonators (GaAs, AlN) for microwave-optical quantum transduction; (2) photonic integrated circuits for quantum sensing; (3) on-chip phononic and photonic crystal devices. Focuses on enabling technologies for quantum repeater nodes and sensors.

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.

Grange leads the Optical Nanomaterial Group at ETH, developing nonlinear materials for quantum photonic integrated circuits. Research directions: (1) Barium titanate (BTO) nanophotonics — scalable CMOS-compatible BTO thin-film integrated circuits exploiting large χ(2) nonlinearity for quantum entangled photon-pair generation via SPDC; (2) Lithium niobate on insulator (LNOI) — quantum photonic integrated circuits for heralded single-photon sources and electro-optic transduction; (3) Second-harmonic generation sensing — SHG-active nanocrystals as contrast agents and phase-sensitive probes in biological imaging; (4) On-chip entangled photon sources for quantum communication and sensing. Strong quantum sensing application in nonlinear optical readout of quantum states.

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.

The Stern Group explores fundamental quantum interactions of photons with 2D materials, nano-scale structures, and atoms. Key thrusts: (1) Valley-selective exciton-polaritons in monolayer transition-metal dichalcogenides (MoS₂, MoSe₂, WSe₂) embedded in optical microcavities — hybrid light-matter quasiparticles with valley-selective polarization and cavity-modified dynamics; (2) 2D semiconductor quantum emitters — quantum-dot-like single-photon emitters formed by confinement in TMD nanoribbons and by chemical functionalization/strain engineering of defects; (3) Astrophotonics: collaboration with Argonne National Laboratory and the Australian Astronomical Observatory to design and fabricate silicon ring-resonator photonic circuits for OH sky-background suppression in near-IR astronomical spectrographs; (4) Quantum non-reciprocal photonics in axisymmetric microresonators. Experimental tools: time-resolved spectroscopy, single-photon counting, nanofabrication. DOE Early Career Award; ONR Young Investigator Award; Sloan Research Fellow 2013.
