Topic: entanglement

Mid-infrared spectroscopy reveals molecular signatures of proteins and lipids, but conventional detection needs specialised equipment. Quantum correlations between differently coloured photons, including entanglement, offer another approach: a mid-infrared photon interacts with the sample while interference enables its information to be measured with visible or near-infrared light. The speakers explain the underlying principle and the progression from quantum spectroscopy to imaging with undetected photons. They discuss their work at the University of Technology Sydney to turn quantum mid-infr

This Perimeter Institute conference brings together researchers studying quantum reference frames, quantum gravity, quantum foundations and related experiments. Topics include relational observables, quantum information in dynamical spacetime, locality, causality, entanglement, and the operational meaning of observers and subsystems. The meeting runs from 26 to 30 October 2026 in Waterloo, Canada. The organizer provides information for virtual participation.

The talk explores a quantitative connection between Huygens’s legacies in wave optics and classical mechanics. Optical polarization, coherence and entanglement are related to mechanical quantities including centre of mass and moment of inertia. Distributions of classical point masses provide a representation of nonseparability in optical fields, and the correspondence extends to quantum states of two qubits. These mappings offer an intuitive way to examine entanglement and the shared mathematical structure of mechanics, classical optics and quantum physics.

The condensed-matter and quantum-information theory groups seek postdoctoral researchers for autumn 2027, with flexible starting dates. Research spans quantum many-body dynamics, entanglement, correlated materials, topology, superconductivity, quantum optics, ultracold gases, quantum simulation and computation. Successful applicants can join international experimental and theoretical collaborations. Pay follows the German TV-L agreement. Submit supporting materials by 22 November 2026; the advert notes that later applications may also be considered.
