Adapting maximum likelihood decoders using just 1% of efficiently learned Pauli error rates via Cycle Error Reconstruction boosts quantum error correction performance up to 10×, helping lower the overhead for fault-tolerant quantum computing. @bartlettquantum.bsky.social

Enhancing Decoding Performance using Efficient Error Learning
Lowering the resource overhead needed to achieve fault-tolerant quantum computation is crucial to building scalable quantum computers. We show that adapting conventional maximum likelihood (ML) decode...

Our suite of efficient and scalable characterisation tools provide a wealth of data on these 156-qubit devices - simultaneous randomised benchmarking, *including* mid-circuit measurements, temporal constency, cross-talk, etc. It's like Christmas for QCVV tragics.

As a bonus, Robin Harper has benchmarked these latest IBM devices (Heron r2) to within an inch of their lives! Check out the Methods section...

We've pushed the limits of the latest IBM devices to see the many ways that quantum logic can fail. We've performed a complementary pair of experiments on a quantum code - one testing memory, the other testing stability - highlighting the key role of mid-circuit measurements in fault-tolerant logic.

I work in the incredible Sydney Nanoscience Hub: a purpose built facility for exploring the frontiers of new technologies such as quantum. And I love showing it off to visitors!

If you’ve sent me an email this year and I haven’t responded, interpret that as you like 🤣
