Last week we have put on arXiv a manuscript where we demonstrate beyond classical computations. We also show that having too many qubits w.r.t. the error rate don't give you any advantage. There is a phase transition where you can efficiently emulate noisy quantum hardware

On their new device, Quantinuum performed a beautiful experiment as well creating Abelian Topological order. I will definitely read it! arxiv.org/abs/2305.03766

Our work on the braiding of non-Abelian anyon (the first experimental realization!) is finally out in Nature. It's quite amazing to see experiments observing these non-Abelian anyons that have escape experimental probe for so long.

Broadbanding of parametric amplifiers is an impedance matching problem. Check out Google Quantum AI Intern Ryan Kaufman (HatLab) work on JPA with 500 MHz bandwidth using filter synthesis techniques arxiv.org/abs/2305.17816

Analogue simulation with transmons has a nice future! It's really exciting to see SC becomes such a nice platform for quantum simulation. Very nice work from Massachusetts Institute of Technology (MIT) EQuS group

We prefer XEB at Google Quantum AI :p Joke aside, I think for elements fidelity everyone has converged to some randomized benchmarking (and variant) and the comparison between plateforme is possible.

The theorist at ⁦Google Quantum AI⁩ have put together a manuscript detailing when quantum circuit are “classically hard”. They also show that the IBM 127 qubits experiment result is indistinguishable from a 28qubits classical simulation arxiv.org/abs/2306.15970

Very exciting to see Noah Goss highlighted for his work on qutrit CZ. This work is particularly close to my heart as it’s the culmination of my time at Berkeley Lab . I really hope that we will see more qutrit results in the future!

Remember that paper from the end of last year that claimed it could factor 2048 bit integers using 378 qubits? At the time, I mentioned to Tanuj Khattar that a nice starter paper would be to just simulate it and verify it doesn't work. Here's the result: arxiv.org/abs/2307.09651

As an experimentalist, seeing our work studied by other is extremely rewarding! I am really happy to see that our work sparked interest in the community!

Two new papers from our team detailing how we optimize our gates and measurements. Our work on beyond-classical computation, Majorana edge modes, non-Abelian braiding and quantum error correction was enabled by these optimizations. arxiv.org/abs/2308.02321 arxiv.org/abs/2308.02079
