Topic: Quantum-physics

Fault-tolerant quantum computation must overcome complex control requirements and substantial error-correction overhead. This talk describes reconfigurable neutral-atom arrays in which optical tweezers coherently transport atoms, enabling any-to-any connectivity, high-fidelity programmable operations and mid-circuit processing in a zoned architecture. Parallel control, transversal operations and long-range connections support experiments ranging from precise quantum-scrambling simulations to a universal fault-tolerant processing architecture. Theoretical methods exploiting reconfigurable conne

This talk develops a first-principles description of interacting electrons, nuclei and electromagnetic fields by extending density-functional theory to quantum electrodynamics. It introduces electron–photon exchange-correlation functionals and photon many-body dispersion, a generalization of molecular dispersion methods that treats electronic and photonic degrees of freedom together. Applications examine anisotropic coupling, effects beyond single photons and cavity-modified van der Waals forces. The approach aims to retain these strong-coupling effects while remaining efficient enough to simu

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.

The School of Physics and Astronomy seeks a researcher in quantum information science, including computation, simulation, algorithms, error correction, sensing, metrology, communication or quantum-device theory. Work incorporating AI or machine learning is encouraged. The appointee will establish an internationally recognized, externally funded programme, teach undergraduate and graduate courses, mentor students and postdoctoral researchers, and contribute departmental service. The full-time position advertises pay of $105,000–$120,000. Applications remain open until filled, with priority give

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.
