ML4Q Workshop on Quantum Computing with Qudits

Overview

Qudits coherently encode quantum information in multiple states, promising unique new opportunities for quantum error correction, quantum simulation, and quantum computing. Many physical platforms naturally host a large number of energy levels, but incorporating them into the quantum information stack poses new challenges for experiment and theory. This workshop will bring together experts and early-career researchers working on quantum computing and quantum error correction with multi-level systems, and researchers from related fields in order to foster exchange and stimulate discussions across disciplines and between experiment and theory.

Date: 21.-23. September 2026

Venue: RWTH Aachen University, Institute of Physical Chemistry, Landoltweg 2, 52074 Aachen

Abstract submission deadline: 16. August 2026

Registration and abstract submission link: https://survey.hifis.dkfz.de/157228?lang=en

Limited financial support may be available for students who would otherwise be unable to attend the workshop. Please contact the organizers if you would like to inquire about possible support.

Diversity, Equity, and Inclusion

We are committed to fostering an inclusive environment and encourage application from a diverse audience of scholars from various disciplines, cultural backgrounds, genders, and stages of their academic and professional careers.

Topics

Mathematical foundation and fundamentals of error correction with qudits
