Happy to see our paper published today demonstrating spin qubit control with integrated milli-kelvin CMOS. Much more of this coming from emergencequantum.com www.nature.com/articles/s41...

nature.comSpin-qubit control with a milli-kelvin CMOS chip - NatureCMOS-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.

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.

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.

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?

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

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. arxiv.org/abs/2411.09919

arxiv.orgHow contextuality and antidistinguishability are relatedContextuality 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...
