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.
TQC 2026 takes place Aug 31 – Sep 4, 2026 in Sherbrooke, Canada.
TQC 2026 is an in-person event.

TQC brings quantum computing theory to Sherbrooke, in Quebec's Eastern Townships, for the first week of September — the cusp of maple season, with warm days, cool nights and the first red edges on the hillsides. Sherbrooke is a compact francophone university city ringed by lakes and low mountains; it is Canada at its unhurried best, and home to one of the country's serious quantum research institutes.
Most international attendees fly into Montréal-Trudeau (YUL) and cover the final 160 km by intercity bus (Limocar, ~2h15 from downtown Montreal) or rental car (1h45 on Autoroute 10 through the Townships). There is no practical rail link, so plan the last leg deliberately — the drive through the Eastern Townships is scenic enough to count as sightseeing. Within Sherbrooke, the city bus network and short taxi hops cover a conference week.
Skip the taxi queue — pre-book a fixed-price airport transfer with Kiwitaxi. Exploring beyond the city? compare rental cars on EconomyBookings.
Canadian roaming charges surprise US and European visitors alike; arrange data before arrival, as Sherbrooke has no airport SIM counter to fall back on. Set up an eSIM with Airalo before you board and you're online the moment you land.
Gorge de la rivière Magog. A river gorge running straight through downtown, crossed by footbridges and lined with a promenade linking Lac des Nations to the old mill buildings. The full loop takes under an hour and is the natural after-session walk — the murals of Sherbrooke's celebrated fresco circuit decorate the route.
Mont-Orford National Park. Twenty-five minutes west, Orford's summit road and chairlift open panoramic views over the Townships' lakes; hiking trails range from lakeside strolls to a proper three-hour summit circuit. Early September means empty trails and the first fall colour at elevation — the region's ski crowd hasn't arrived yet.
North Hatley and Lake Massawippi. The prettiest village in the Townships sits on a glacial lake twenty minutes south — verandahed inns, a general store from another century, and lake swimming that holds its summer warmth into September. It is the canonical half-day drive for visiting academics, ideally ending with dinner on a lakeside terrace.
How do I get to Sherbrooke from Montreal airport?
Limocar buses run from downtown Montreal (reachable from YUL by the 747 shuttle) in about 2h15, or rent a car at the airport for a 1h45 highway drive. Groups often share a rental — it also unlocks the Townships after hours.
Is English enough in Sherbrooke?
The university and conference environments are fully bilingual, and service staff manage English with visitor-town patience — but opening with a bonjour goes a long way in Quebec's most francophone region outside Quebec City.
