Topic: Quantum Information

Two postdoctoral researchers will study semiconductor quantum devices in the Quantum Functional System Research Group, led by Seigo Tarucha at the RIKEN Center for Emergent Matter Science. The work concerns silicon qubit characterization, multi-qubit systems, high-fidelity quantum operations and scalable quantum computing within Moonshot R&D Goal 6. Applicants need a doctorate in an experimental field such as semiconductor physics, quantum transport, electrical engineering or quantum information, or must obtain it before starting. The one-year appointment is renewable following evaluation,

Supports fundamental physics through atomic, molecular and optical science; nuclear and particle physics; gravitation; plasma physics; living systems; quantum information; instrumentation and related programmes. Proposals are accepted at any time, with programme-specific target dates for review. Funding levels and duration vary; the solicitation does not promise a fixed individual award. Investigators should contact the relevant programme about overlapping proposals or existing Physics awards.

Perimeter invites new and recent PhDs in fundamental theoretical physics to pursue independent research in its interdisciplinary Waterloo community. Research areas span cosmology, mathematical physics, particle physics, quantum fields, gravity, quantum information and quantum matter. Support includes research and travel funding, healthcare, visiting collaborators and mentoring. Joint fellowships with partner institutions may be available. Submit a CV, publication list, research statement and at least three recommendation letters through AcademicJobsOnline. The application listing gives Novembe

MIT’s Center for Theoretical Physics, a Leinweber Institute, seeks postdoctoral fellows starting September 1, 2027. The broad search covers quantum field theory, gravity, strings, cosmology, particle and nuclear theory, strong interactions and quantum information, including connections across these fields. Independent research directions are welcome; close matching to a faculty programme is not required. Candidates must first be nominated by a faculty member or equivalent senior industry researcher by October 9, 2026 at 11:59 p.m. US Eastern Time. Nominees then apply through AcademicJobsOnline

The Anthony J. Leggett Institute for Condensed Matter Theory seeks postdoctoral researchers for Fall 2027. The Leggett fellowship is renewable for up to three years; Moore fellowships offer broad research choice in condensed matter theory and quantum materials. Interests include strongly correlated materials, topology, nonequilibrium physics and quantum information. Fellows collaborate with Illinois theorists and experimentalists, with access to materials, quantum-science and computing facilities. A single application covers both fellowships and related institute positions. Submit by October 1

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.

Aram Harrow connects the Unique Games conjecture, especially small-set expansion, with the quantum separability problem. The Lasserre hierarchy used for Unique Games and the k-extendible relaxation of quantum separability turn out to be closely equivalent algorithmic approaches. The talk examines how quantum-information conjectures could yield quasipolynomial algorithms or hardness results for Unique Games, and discusses promising research directions. It introduces the necessary quantum mechanics, Unique Games, and hierarchy background rather than presupposing it. The presentation draws partly
