QEC25 marks the 7th International Conference on Quantum Error Correction, a prestigious biennial event that has been a cornerstone of the quantum research community since its inception in 2007. Previous editions have been hosted in leading international cities, including Los Angeles, California; Zurich, Switzerland; Washington, District of Columbia; London, UK; and Sydney, Australia. For the 2025 edition, the conference returns to the United States, proudly hosted by the Yale Quantum Institute.
This conference will convene distinguished experts from academia and industry to explore cutting-edge research in theoretical, experimental, and technological advancements towards achieving robust quantum computation. Key topics will include quantum control, error correction, fault tolerance, and their intersection with physics, computer science, and technology.
Scheduled from Monday, August 11 to Friday, August 15, 2025, QEC25 will take place at the Yale Quantum Institute in New Haven, with an anticipated attendance of 400 quantum researchers. A tutorial session will be offered for students and anyone interested the day before, on Sunday, August 10, 2025.
The following scientists will give invited talks during the conference, listed by alphabetical order.
Update June 3, 2025: To accommodate the very large number of submissions to the conference, we have added a 3rd poster session.
All attendees, speakers, poster presenters, and sponsors should register to attend the conference. To ensure a safe and enjoyable conference to all attendees, the registration is capped at 483 persons, due to the auditorium maximal capacity. Register early to ensure your seat (the registration will close completely should we reach 483 attendees), and benefit from the preferential rate.
To allow QEC23 attendees a stress-free (and car-free!) conference, we offer a preferential rate of $189/night at the Omni Hotel, located in downtown New Haven, 1.5 blocks from the Yale University campus. This early bird rate is available for attendees until June 9. All rooms offer free cancellation before August 8.
Thank you to our sponsors for making this conference possible
and keeping our registration fee low and accessible to all the QEC community.
Yale University has been at the forefront of quantum science and engineering since the early 1990s, serving as the birthplace of significant quantum breakthroughs, particularly in circuit quantum electrodynamics. Recognizing the critical importance of quantum error correction early on, the Yale Quantum Institute has cultivated a vibrant ecosystem of experimental and theoretical researchers dedicated to advancing fault-tolerant quantum computing.
Sponsoring the QEC25 conference at Yale offers a unique opportunity to engage with the next generation of quantum researchers and contribute to discussions on quantum error correction at the very site where some of the field’s most significant breakthroughs have occurred.

Peer review: insights on how to participate and benefit
Peer review is a crucial part of science. Effective engagement with peer review, both as author and referee, is an important part of being a successful scientist. In this tutorial, you will learn more about how to be an active participant in the peer review process from editors at PRX Quantum.
The tutorial consists of informative tips and a short practice/Q&A. Participants will learn the benefits of being a referee, how to act as one, and how to successfully interact with editors and referees for the manuscripts they author.

Tesseract: A Search-Based Decoder for Quantum Error Correction
Tesseract is a high-performance decoder designed to support a broad class of quantum error correction codes and fault-tolerant protocols. It enables researchers to quickly prototype, simulate, and benchmark decoding strategies under realistic circuit-level noise, making it a practical tool for both theoretical and experimental QEC work.
