Microsoft’s release in February of a technical paper on Nature as well as a post of a pre-print paper discussing Roadmap to fault tolerant quantum computation using topological qubit arrays on arXiv has generated a lot of discussion amongst quantum physicists and others on the viability of this approach. In order to provide additional information about their work on this technology, Dr. Chetan Nayak gave a presentation at the recent APS 2025 conference in Anaheim, California with supplementary data that provides further insight into Microsoft’s work.
Later that day, GQI sat down with Dr. Nayak to further discuss this technology and, in particular, provide a glimpse into further improvements the Microsoft team is planning to reduce error rates, increase the topological gap, and integrate the topological device into a full quantum computing system.
As a service to our readers, GQI is posting a recording of the APS presentation along with our follow-on interview so our readers can understand more about this technology. You can access videos for both of these sessions on the GQI website HERE.
For those who missed our earlier report on Microsoft’s announcement you can view see our report HERE. Also, GQI has just created a more detailed technical assessment of Microsoft’s topological technology for our clients. Those interested in obtaining access to this assessment can send a request to [email protected].
