Let me try to explain why it's important to study the foundations of quantum mechanics. (1/n)

(Have to do some breathing exercises, b/c to me it's blindingly obvious that "understanding the most important theory in physics" is something physicists should care about, but apparently opinions differ.)

Simulating quantum chaos without chaos Quantum chaos is a quantum many-body phenomenon that is associated with a number of intricate properties, such as level repulsion in energy spectra or distinct scalings of out-of-time ordered correlat...

What's the jurisdiction of Betteridge's Law with respect to academic articles?

The second to last afternoon session of #QCTIP2025 features great talks on classical shadows to estimate properties of quantum systems.

It's lunchtime on Day 3 and now seems like an excellent time to thank our wonderful sponsors who supported, participated in, and made this event happen! #QCTiP

Our second plenary session has Nathan Wiebe both captivating and entertaining our audience -- showing how exponential improvements in gradient-based quantum optimisation are possible. The trick? Don't look at your gradients, go fully quantum! #QCTiP

Had been feeling like there weren't enough Fermions so let out a big sigh of relief when Alexander Schuckert came up to tell us about fermion-qubit fault tolerant quantum computing in the Hahn Hall #QCTiP

Marcel explains the task of single-copy stabilizer testing and a lower and upper bound on the sample complexity.

Congratulations Senrui! Great news 😃

The doors to #QCTiP2025 are about to open! From next Wednesday to Friday, Berlin will host the largest international conference on quantum computing theory in practice—at the beautiful and historic Harnack House, where Schrödinger, Einstein, and Planck once came and went.

Saw Squid tonight, that song was Narrator 👌

Every concert you attend you get one (1) song for which you can take out your earplugs

Superdense coding is now just coding 😢

How Schrödinger’s Cat Got Famous Fifty years ago, science-fiction writer Ursula K. Le Guin popularized physics’ most enigmatic feline.

Schrödinger originally invented the cat image as a gag. But with the help of science-fiction writer Ursula K. Le Guin, it became the most well-known quantum mechanics thought experiment. 🧪

Lucky I remember middle names. Video is sick btw

No guarantee that all the tickets will last, better be quick!

… Sam?

The registration deadline of the main event of the year on quantum computing theory in practice (#QCTiP2025) will be #tomorrow, anywhere on Earth.

After the smash hit debut album "NISQ", @preskill.bsky.social releases his long-awaited sophomore project "Megaquop".

Critics laud the forward thinking and maturity evident in this release but wonder -- can lightning be caught in a bottle twice?

Fully agreed. Forget about scrutinising: focus on the obvious misdirection

I’d believe that but not knowledgeable enough to make the call. But whether true or not I think the message needs to be that this is an unacceptable way to go about it

Appreciate @spinespresso.bsky.social, @dulwichquantum.bsky.social + others on the case

Wherever the evidence is “released”, the confusion was intentional and this is a failure of integrity of everyone involved

The more I think about it, the more cynical I am about making press releases about a certain claim coincide with a Nature paper that claims something materially different. Even if they end up factually correct, this is the heart of the issue with mixing capital interests and science

Time to register and book your trips to Berlin, tickets are hot and selling fast!

For a list of accepted talks, see the below link--looking like a stellar program 🤩

Oh dear, I hope you can at least cancel/refund the other policies...
