Bøttcher builds hybrid superconductor-semiconductor (Al/InAs) devices and develops new circuit-QED-based quantum sensing tools to probe emergent phases -- unconventional pairing, topological superconductivity -- in 2D and mesoscopic quantum materials that are difficult to access with conventional transport measurements.
Bramati leads the Quantum Fluids of Light team at LKB, studying exciton-polariton superfluids in semiconductor microcavities: quantized vortices, dark solitons, half-solitons behaving as magnetic monopoles, and analogue-gravity phenomena in polariton and photon fluids. The group also develops single-photon sources based on nanoemitters and coordinates the international Q-GAP program with Singapore's NRF on quantum fluids and photonics.
Branton is a pioneer of nanopore sensing, having shown that single DNA/RNA molecules threading through a nanopore produce ionic-current signatures usable for single-molecule sequencing — foundational work underlying the modern solid-state and biological nanopore-sequencing industry, and a direct fit to the biosensing/single-molecule filter criterion.
Brantut's lab studies quantum transport in ultracold Fermi gases, using them as quantum simulators for nanoscale solid-state devices. Research directions: (1) Mesoscopic quantum transport — fermionic cold atoms transported through quantum point contacts, studying conductance quantization, shot noise, and thermoelectric effects in atomic-scale channels; (2) Fermionic superfluidity in confined geometries — observing and probing pairing in constrictions; (3) Dissipation and open quantum systems — controlled introduction of loss to study non-Hermitian quantum physics; (4) Quantum thermometry in ultracold systems — using transport signatures as precision thermometers. Analogous to quantum Hall measurements and nanoelectronics in an ultra-clean platform.
Tulio Brito Brasil focuses on multimode quantum optics, squeezed and entangled states of light, and their application for quantum sensing and communication. Research: (1) generation of two-colour high-purity EPR photonic states; (2) squeezed light for quantum noise reduction in measurement; (3) continuous variable quantum optics protocols for networks. Recently joined QUANTOP at NBI.
Brasselet is a CNRS researcher at Institut Fresnel developing polarization- and orientation-resolved fluorescence microscopy, using controlled excitation and detection polarization states to map the 3D orientation and organization of fluorescent probes and biomolecular assemblies (e.g. lipid order, amyloid and cytoskeletal structures) at and beyond the single-molecule level, including recent work on the mathematical foundations of polarimetric microscopy.
Breeze is a senior research fellow at UCL working on room-temperature solid-state masers. Research directions: (1) Pentacene maser — first demonstration of a room-temperature, continuous-wave solid-state maser (Science 2018) using photoexcited triplet-state pentacene in p-terphenyl crystal; achieving amplification with noise temperature near 1 K; (2) Diamond NV maser — developing NV-center-based maser for ultra-low-noise microwave amplification at room temperature, relevant to quantum sensing readout chains; (3) Maser applications — quantum-limited amplification for dark matter searches, MRI signal amplification, and quantum communication repeaters; (4) Spin dynamics — understanding triplet-state dynamics in organic crystals for spin polarization control. Strong relevance to quantum-limited microwave sensing.
Bretenaker (former LuMIn director) works on laser physics and quantum optics: sub-shot-noise sensing with phase-sensitive-amplifier-generated entangled beams, spin-noise spectroscopy in atomic vapours, EIT slow light, and quantum-limited passive resonant (fiber/bulk) gyroscopes with Thales. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work represents the fundamental-light and quantum-limited-rotation-sensing side.
Briant works in LKB's optomechanics and quantum-measurement team, using high-finesse Fabry-Perot cavities coupled to mirror/membrane mechanical resonators to study radiation-pressure back-action, quantum noise, and force sensing near the standard quantum limit, alongside Pierre-Francois Cohadon and Antoine Heidmann.
Daan Brinks develops all-optical electrophysiology tools for neuroscience. His lab engineers genetically-encoded voltage indicators (GEVIs) and combines them with optogenetics to read out and control neural circuit activity. Key directions: (1) engineering bright, fast GEVIs with improved photostability and voltage sensitivity; (2) multiplexed all-optical neural circuit mapping; (3) identifying rare aggressive cancer cells using voltage-sensitive dyes. His voltage imaging approach represents cutting-edge biosensing at the intersection of photonics and neuroscience.
