The problem of disambiguation or researchers is valuable.
Google could solve this instantly by including the ORCID in profiles or copying the idea. (Sadly rumors suggest Google scholar is likely to be axed.)

ORCID launched more than a decade ago, but has yet to fulfil its potential
Many author-identifier profiles are ‘empty’, making it difficult to track who’s publishing what.

arxiv.org/pdf/2407.07694
Laserless single (99.99916) and two-qubit (99.97) gates. They bring a new paradigm for a platform that’s been going strong for 20+ years
(Also enjoy the integrated form factor)

At QTML 2024, I spoke about recent work with Robert Huang on "Learning shallow quantum circuits with many-qubit gates" (a.k.a. efficient learning of QAC^0 unitaries). In this ~15min talk I discuss the project motivation, key results, and high-level proof ideas.

The thing I've noticed about quantum press releases is at the core there is usually a solid advance.
Unfortunately it gets butchered and hyped.
E.g. Nvidia and Google's recent releases.

Google's new hardware looks great and I'd be excited to try it out. But I seem to be even more interested in its limitations: Their repetition code results show an error floor at around 10^-10.
What physics is lurking down there? Can we tame it?

Google's new quantum computing chip Willow holds lots of promise and its error correction capability is a signature result. But the benchmark Google are using for its performance is, as their team told me, still an "IOU" for more practical calculations www.newscientist.com/article/2459...

New paper today!
scirate.com/arxiv/2411.1...
We run repetition codes of up to d=51 and 100 rounds. But rather than just taking the bit values from the measurement, we take the point on the IQ plane. Decoding using this information gives significant improvements, including passive leakage reduction.

this is cool as
(1) they can operate 1K rather than mK - a huge advantage,
(2) there is less noise at 100GHz,
(3) microwave to optical transduction should be easier
