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...

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

Field trip! We had this week’s reading group on qLDPC codes at the Sydney offices of Iceberg Quantum. Thanks Felix Larry and Sam for hosting, and @universal-soup.bsky.social for organizing

Spin-qubit control with a milli-kelvin CMOS chip - Nature CMOS-based circuits can be integrated with silicon-based spin qubits and can be controlled at milli-kelvin temperatures, which can potentially help scale up these systems.

Happy to see our paper published today demonstrating spin qubit control with integrated milli-kelvin CMOS. Much more of this coming from emergencequantum.com

Terry Rudolph @psiquantum.bsky.social is writing about ‘blocklets’! I got a sneak preview of these from Daniel Litinski and they are very cool.

Emergence Quantum: a commercial 'special ops' team for research and development Professor David Reilly and Dr Thomas Ohki have launched Emergence Quantum, a spinout from the University of Sydney, building on their work at Microsoft Quantum, they are delivering a new type of comme...

A first-of-its-kind research and development company has been launched by the @sydney.edu.au quantum technology team that worked closely with Microsoft Quantum for the best part of a decade.

Emergence Quantum is delivering quantum technology’s “missing link”.

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.

Excited to share our first major result from our IARPA Entangled Logical Qubits team!

Spotted in the wild! ❤️

Now with a cool logo! #Coogee2025

February in Sydney means quantum at the beach! Looking forward to another fantastic Sydney Quantum Information Theory workshop at Coogee. #Coogee2025

Submissions for QEC 2025 are now open through March 28.

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

The deadline for talk submissions at QCTiP 2025 is coming up! Consider submitting a talk until January 10.

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

Last day of work before the holidays and I’ve accomplished the impossible!

Yeah, what @ccanonne.bsky.social said!

Roadtrip! Heading from @equscoe.bsky.social EQUS workshop in Noosa to the @psiquantum.bsky.social Brisbane office opening, with Tom Stace and Andrew Doherty. In Gerard Milburn’s car! Going to be a very #quantum drive

Google’s quantum computer takes major leap forward Google Quantum AI has managed a new milestone in quantum computing, with chips that can correct errors below a “critical threshold”.

Cosmos Mag has my take on today’s Google QEC result in @natureportfolio.bsky.social
Awesome result everyone! #quantum cosmosmagazine.com/science/phys...

Great to have Prof Ian Walmsley visit us at Sydney Nano. We are both thinking about similar things: how to create research facilities and places that enable great science and new collaboration. Shared facilities for nanofab, HPC, etc are standard, but how can it work for quantum labs? Any ideas?

Mitigating errors in logical qubits Communications Physics - Quantum error correction produces an enormous amount of data about the quantum system, including information about whether an uncorrectable error is likely. In this work...

Post selection in QEC is not cheating 🤣, but can be scalable and significantly reduce your resources overheads! Check out our newly published paper in @commsphys.bsky.social rdcu.be/d1LuM, a great collab with Sam Smith and @benbrown.bsky.social @sydneyphysics.bsky.social

Closed timelike curves -> nonlinear quantum mechanics -> all sorts of absolutely crazy shit

At Australian Parliament House for a Parliamentary Friends of Science event. Great to see bipartisan support for science and tech … and what a great venue!

Celebrating a great 2024 with the Sydney Quantum Academy. Thanks Peter Turner and SQA team! #quantum

How contextuality and antidistinguishability are related Contextuality is a key characteristic that separates quantum from classical phenomena and an important tool in understanding the potential advantage of quantum computation. However, when assessing the...

Did you know that contextuality of a set of quantum states is precisely captured by notions of antidistinguishability? Find out more in our new paper. Great collaboration with USYD PhD student Maiyuren Srikumar and the brilliant Angela Karanjai.
