please reach out with any questions/comments!

this technique also works for surface code memory experiments, where training on data with 10x error rates is optimal (but 20x higher is still better than data sampled from the device at its true error rate and MWPM!). The optimal (weirdly) corresponds with when MWPM breaks down:

This behavior holds for repetition codes (across hyperparameters, initializations, architectures), which the theory predicts:

I put out a preprint on machine learning for QEC decoders with some theory about importance sampling for decoding. Takeaway: You can robustly improve ML decoder performance by training on data generated with higher device error rates, sometimes 10x higher! arxiv.org/abs/2505.22741

This past week, I received a second stop work order on one of my grants. This now means that we can no longer spend on *two* of my major grants. Several of my group members will now graduate earlier than expected, I am looking into being a consultant for the summer, and students will do internships

The research group of Prof. Christoph Hirche @christophhirche.bsky.social at the University of Hannover (Germany) is looking for a motivated PhD student.

so begins a revolution in inline formatting. My submission is 2xp(-β H) / Tr[2xp(-β H)] :D

Submissions for QEC 2025 are now open through March 28.

This will easily be the most exciting conference on quantum error correction yet!

Quantum Computing Stack Exchange has the potential to be a resource of great value, but the only source for its value is its users (not unlike Bluesky). So I hope some will consider participating, whether by asking or answering questions or just giving some upvotes.
