Quantum Mechanics

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. Registration is currently open, and the organizer provides information for virtual participation.

IMPRS-CMS in Stuttgart is accepting applications for multiple fully funded doctoral positions across quantum materials, electronic structure and many-body theory, nanoscience, solid-state spectroscopy, solid-state ionics and batteries, bioinspired materials, quantum and organic electronics, and ultracold atomic gases. The English-language programme provides structured training, individual supervision and co-supervision, mentoring, research infrastructure and additional support for scientific meetings and training. The current call remains open through 30 September 2026.

Develop and apply quantum resource theory for Extended Wigner’s Friend scenarios, where the presence of another observer can affect measurement outcomes. The work involves analytical quantum information and probability theory, together with numerical simulation, and relates to Bell nonlocality. This FAPESP-funded doctoral position is expected to start in March 2027. Apply by 16 November 2026 with a CV, a motivation letter of up to two pages and contact information for two academic referees, following the official advertisement.

RIKEN's Quantum Information Physics Theory Research Team is recruiting multiple researchers to conduct theoretical work across quantum computing, superconducting qubits, quantum optics, photonics, machine learning, quantum open systems, computational physics and condensed-matter physics. Appointments are available at senior research scientist, research scientist and postdoctoral levels, with duties scaled to experience. The official call is open until the positions are filled.

Debashree Ghosh discusses quantum-chemistry approaches for strongly correlated polyaromatic hydrocarbons, including acenes and carotenoids. The talk examines why large valence active spaces are needed to describe optical properties and singlet–triplet gaps, and how density-matrix renormalization-group methods address these systems. Changes in molecular topology and odd-membered rings are connected to spin frustration and optical behaviour. The seminar also covers neural-network configuration interaction, connections between artificial neural networks and matrix-product-state wavefunctions, and restricted-Boltzmann-machine approaches to quantum wavefunctions. Applications include singlet fission and multiexcitonic phenomena. The hybrid event takes place in ICTP’s Euler Lecture Hall and online; the official event page provides the registration link.
