IEEE Quantum Week 2026 is bringing the largest quantum computing conference program ever assembled to Toronto next month, with 372 technical papers, 47 workshops, and 12 keynote speakers representing every serious approach to building quantum computers. The six-day event, running September 13 to 18 at the Metro Toronto Convention Centre, reflects how far quantum computing has moved beyond laboratory curiosity into a field where competing technologies, business models, and applications are all racing forward simultaneously.

The scale of this year's program tells a story about where quantum computing stands in 2026. Technical papers have grown by more than 40 percent compared to last year, while workshop papers have more than doubled. The conference is no longer a niche gathering of physicists; it has become a meeting place where 60 percent of attendees come from industry and government, while 40 percent represent academia. Students make up roughly a quarter of the total attendance.

Which Quantum Computing Technologies Are Actually Competing?

One of the most striking aspects of IEEE Quantum Week is its refusal to pick winners. The conference remains agnostic about how a qubit should be built, and that neutrality reflects the reality on the ground. The technologies and engineering track alone covers superconducting qubits, trapped-ion systems, silicon qubits, quantum dots, neutral atoms, and photonics. The algorithms and applications tracks add adiabatic computation and quantum annealing to the mix.

This diversity shows up directly in the keynote lineup. The 12 speakers leading the program represent the full spectrum of approaches currently being pursued by major companies and research institutions:

• Trapped-Ion Systems: Rajeeb Hazra, president and CEO of Quantinuum, will speak on error correction, while John Gamble and Martin Roetteler from IonQ will discuss engineering quantum systems for real-world impact.
• Photonic Quantum Computing: Christian Weedbrook, founder and CEO of Xanadu, will present on scaling photonic quantum computing from the company's Toronto headquarters.
• Superconducting Hardware: Ali Javadi-Abhari, head of Qiskit at IBM Research, will address software for scaling quantum advantage across superconducting platforms.
• Control Electronics and Infrastructure: Niels Bultink of Qblox will discuss building the quantum infrastructure layer that all these systems depend on.
• Enterprise Strategy: Krysta Svore of NVIDIA and Matthias Troyer of Microsoft will explain how large enterprises are setting their quantum computing timelines.

The presence of three sitting chief executives among the keynote speakers underscores how quantum computing has moved from pure research into a competitive commercial landscape. Hazra, Weedbrook, and Bultink all run companies actively building quantum hardware or the systems that control it.

What Do the Keynote Speakers Represent About Quantum's Current State?

The keynote lineup also reveals which companies have achieved enough momentum to command a platform at a major conference. Quantinuum, which listed on Nasdaq in June 2026, priced its shares at $60 each, above its initial guidance range of $53 to $55, and raised $1.68 billion in an upsized offering. By the close of its first trading day, the company was valued at $15.7 billion.

Xanadu, which went public on Nasdaq and the Toronto Stock Exchange under the ticker XNDU after a business combination, has entered discussions for up to $390 million Canadian dollars in support from the governments of Canada and Ontario. The company also developed PennyLane, an open-source quantum machine learning library released in 2018 that has become widely used in the field.

IonQ, which became the first publicly traded pure-play quantum computing company when it began trading on the New York Stock Exchange in September 2021, will have two of its executives speaking at the conference. Lisa Lambert, vice president of global strategy and managing director for Canada, recently transitioned from leading Quantum Industry Canada, where she served as the inaugural chief executive and built the organization into the national voice of the Canadian quantum sector.

How to Navigate IEEE Quantum Week 2026 as an Attendee

If you're considering attending or following the conference, here's how to make sense of the sprawling program:

• Keynote Sessions: Ten sessions run across the six days, with morning sessions from 8:00 to 9:30 a.m. Eastern Daylight Time and evening sessions from 5:00 to 6:30 p.m. Tuesday morning features a joint IonQ session with three speakers and two talks, making it a concentrated look at one company's vision.
• Workshop Format: Each workshop takes 20 to 50 participants and runs as three 90-minute sessions emphasizing discussion over presentations, giving attendees direct access to the people actually building quantum systems.
• Technical Depth: Nine peer-reviewed technical tracks run from photonics and device engineering through algorithms, software systems, machine learning and networking to applications and industrial case studies, each treated at the depth of a full IEEE conference rather than a trade show.
• Career and Networking: The conference includes a career fair and structured student mentorship alongside research sessions, making it useful for both established researchers and people entering the field.

The conference also runs research and commercial sessions side by side. Workshops, tutorials, and technical papers carry the research content, while panels, exhibits, and the career fair cover the business and hiring side. This dual focus reflects how quantum computing has matured from a purely academic pursuit into an industry with real hiring, investment, and product development.

Travis Humble, director of the Quantum Science Center at Oak Ridge National Laboratory, will speak on unleashing quantum acceleration from architectures to applications. Alán Aspuru-Guzik, who works on quantum chemistry and machine learning at the University of Toronto and NVIDIA Research, will also present, though his talk title has not yet been published.

The growth of IEEE Quantum Week reflects a field that has moved decisively past the credibility crisis of earlier years. The conference now attracts enough serious work, enough competing approaches, and enough commercial investment to fill six days with substantive technical content. Whether you're tracking which quantum modality might win out, looking to understand where the software and algorithms stand, or trying to figure out where quantum computing actually creates value, the keynotes and technical program at this year's event will offer the most comprehensive snapshot available of where the field stands in late 2026.
