TQC 2026

About

TQC 2026, the Conference on the Theory of Quantum Computation, Communication and Cryptography, is a leading international scientific conference held in Sherbrooke, Québec. The event brings together theoretical quantum information researchers to present advances across quantum computation, quantum communication, and quantum cryptography. The 2026 edition expects over 300 participants across five days, with a programme built around four invited talks and 87 contributed presentations selected through peer review. TQC occupies a specific and important position in the quantum calendar: where commercial quantum events emphasise hardware milestones and applications, TQC is dedicated to the underlying theory — algorithms, complexity, protocols, and cryptographic foundations. Attendees are largely academic researchers, doctoral students, and theoretically-oriented industry scientists engaging directly with current results. The contributed talk programme provides a detailed picture of where quantum information theory is actively progressing. For anyone working on the theoretical foundations of quantum computing and post-quantum cryptography, TQC remains a central annual venue.
