When wonderful people do wonderful things for our understanding of the universe, it is a great day. Congrats Dr Chiara Mingarelli and everyone involved!

Wow. Justice Ketanji Brown Jackson dissent.

If you are ⁦Comic-Con International⁩ in San Diego this year, don’t miss this great panel about the benefits of getting scientists involved in the making of movies and shows (Marvel, Star Trek, Jurassic, and more). Some pretty big names in there. #ComicCon

Confusion over the black hole firewall paradox accelerated a synthesis of quantum gravity with quantum information and quantum matter. It's cool that much of the recent progress has been driven by "up-and-coming theorists." quantamagazine.org/new-calculatio…

It's as close to official as we'll probably get: LK-99 is likely simply a ferromagnetic material, which explains its levitating properties, according to new research from Peking University. The room temperature superconductivity revolution will have to wait another day.

Today Caltech we celebrated the groundbreaking for the Ginsburg Center for Quantum Precision Measurement. It has been an exciting day! quantumfrontiers.com/2023/08/10/cal…

More of this please.

I watched the Barbie movie last week, then Slate interviewed me about it. A surprisingly good read.

IQIM rides again! My colleagues and I are excited by this opportunity to make more great discoveries in our next 6-year cycle. Thanks, U.S. National Science Foundation and Caltech, for supporting IQIM, and thank you Whitney Clavin for the nice article. caltech.edu/about/news/cal…

☃️Is it easy to find local minima?☃️ When a physical system is cooled❄️, Nature doesn't always find the ground state but finds a local minimum In arxiv.org/abs/2309.16596, we prove that a machine that can cool things to local minima is a universal quantum computer (1/9)

What do you do if your measurement device is noisy, but you need to squeeze as much information out of whatever is about to hit your detector? You “reshape” the signal in a way that is optimal for detection. That way you can fit a square quantum peg in a round hole.

"The broader lesson of Regev’s new algorithm, beyond the implications for factoring, is that quantum computing researchers should always be open to surprises, even in problems that have been studied for decades." quantamagazine.org/thirty-years-l…

Will there be Quantum Advantage in the next 5 years? If not, why (which theoretical and/or technical hurdles need to be overcome)? If yes, which industry will benefit first (academia counts too)?

In quantum error correction, stabilizer codes using a set of *commuting* measurements (such as the toric code or surface code) have been the go-to solution for topological quantum memories — despite the need for multi-qubit measurements. 1/7
