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.)

Nature (and @lizziegibney.bsky.social) take a more-than-usually systematic look at the greatest failure of modern physics: the fact that we can't even agree on what quantum mechanics says.
And the leader is an approach that is notoriously not well-defined. Ugh.

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

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

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

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?

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
