About The Conference

Superconducting Qubits and Algorithms (SQA) is a not-for-profit scientific conference with a focus on science, technology, and algorithms relevant for superconducting quantum computers. It is organized by IQM Quantum Computers in co-operation with the scientific community. Our goal is to make this the leading event in its field.

SQA is an official satellite conference of LT29.

  • Absolutely. We still invite you to submit your talk or poster to discuss it with the scientific community.

  • Actually, we do! The selection of scholarship recipients is based on need and your submission. There is a separate gremium deciding on that.

  • This conference is held on-site only. But we will live stream the conference.

  • The organizers of the SQA Conference 2022 are taking all measures to make the event safe. Thus, the venue and the partners we have chosen to work with on this event have implemented specific sanitary protocols ensuring the safety of all employees and visitors. We will follow the official Finnish guidelines for large in-person gatherings at the time of the conference. The up-to-date guidelines can be found here.

Get Updates

We will inform you only about relevant updates (such as deadlines) concerning the SQA conference – promise!


All tickets are sold. The waiting list is now also closed. Registration fees include coffee break in the morning, lunch, coffee break in the afternoon, conference dinner on Saturday, and excursion. Travel and accomodation need to be booked separately. The number of tickets is limited. For attending the live stream, you do not need to register.
