Watch Oskar Painter's presentation from Quantum Korea in Seoul. As Director of Quantum Hardware at AWS Center for Quantum Computing, he discusses the 'quantum tyranny of numbers' & forecasts major quantum error correction advances www.youtube.com/watch?v=Ojnf... #QuantumComputing #AWS

Lindblad is for everyone! arxiv.org/abs/2506.22436

A major milestone in my career, as one of the self-appointed knights of quantum.

Raymond Laflamme 1960-2025. A great scientist, renowned for his pioneering contributions to quantum error correction. A great leader, founding director of the Institute for Quantum Computing. A great colleague and teacher whose legacy continues to inspire us. uwaterloo.ca/institute-fo...

He's right. "Nothing short of devastating" By @holdenthorp.bsky.social @science.org www.science.org/doi/10.1126/...

Michael Roukes kicking off #FNS2025, going back 30 years to the beginning of NEMs. (explaining this paper arxiv.org/abs/2505.04574 which was then rejected by APL!)

The building committee gets a first look at the basement of the Ginsburg Center for Quantum Precision Measurement at Caltech. We're standing where a tunnel will connect Ginsburg labs to labs in neighboring Downs Laboratory. With me are Nick Hutzler, Rana Adhikari, Michelle Effros, and Dave Hsieh.

New paper out! We resonantly couple a superconducting heavy-fluxonium qubit ⚛️ to a macroscopic membrane 🥁 oscillating at a few MHz. ~300 repeated interactions let us track its quantum motion, observe back-action & probe non-commuting operators. Diósi–Penrose next? (1/8) arxiv.org/abs/2505.21481

At the beautiful Les Houches for a workshop on TFLN #photonics 💡 Here are my lecture notes: quantum-noise.ghost.io/les-houches-...

Big: The final version of a randomized, controlled World Bank study finds using a GPT-4 tutor with teacher guidance in a six week afterschool program in Nigeria had "more than twice the effect of some of the most effective interventions in education" ("equating to 1.5 to 2 years" of standard school)

Morning prayer for the faithful

These notes are amazing, just the right amount of detail and insight! Thanks!

Every time I am tempted and I start using Markdown + Tex equations, after getting to document that’s more than 2 pages long I just end up coming back to full LaTeX.

A collaboration between the Moerner and Qi Labs has produced a tool to track real-time genome dynamics in living cells — combining single-molecule imaging + CRISPR innovation. 🧬 🔗 chemistry.stanford.edu/news/new-too... #MoernerLab #QiLab #GenomeImaging #CRISPR

And here’s my first post :) Ever wondered what “free energy” is?

I decided to make a website. I’ll post stuff on it every once in a while.

#maddow Science break. This kayaker gets approached by an otter every time he visits a lake. The otter was orphaned after the mother was in an accident, and the man helped it throughout it's rehabilitation process to later release it back into the wild. Volume up.🔊

We press forward with determination, grounded in the values that have made us a trusted and effective advocate for ocean conservation. We lead with hope. The path may not always be straight, but our commitment and belief in humanity’s ability to come together and heal the planet is still unwavering.

If you are interested in quantum computing, I strongly recommend this insightful article by @caltech.edu student @robbieking1000.bsky.social calling for a "scrappier approach" to finding new applications. quantumfrontiers.com/2025/04/20/q...

I've been revamping and updating my collection of selected references to topics in quantum information on my homepage. Comments, feedback and suggestions welcome! felixleditzky.info/selected_ref...

Crazy!

This might be the most useful thing I have come across in social media - a personalized feed of academic papers filtered by your follower network! Highly recommend. #academicsky

OK- here we go. Sorry for the delay, I was not prepared for the exertion required in the thrill-a-minute adventure that is… CACAO FERMENTATION. Yes, this will actually take 5 days. After that two days of drying. I’m not making this up. Nothing happens. Really. You’ll see. Anyway, off we go!

Our paper that tells you how to make millisecond transmons just appeared. Congrats Matthew, Faranak, and team! In collaboration with Nathalie de Leon and Bob Cava, and building on five years of work in C2QA, one of the five DOE National Quantum Initiative Centers. arxiv.org/abs/2503.14798

Thank you @vvsmider.bsky.social for sharing this story.

I have been so excited since I found out this would be announced today! RIP any ability for me to concentrate: www.apple.com/tv-pr/news/2...

Amazon team claims its Ocelot chip could speed up the development of a large-scale, fault-tolerant quantum computer by 3‒5 years. 🧪⚛️ physicsworld.com/a/cat-qubits...

Please share widely. Firing of excellent scientists by political appointees with zero oversight is outrageous. This requested pushback from congress is essential to maintain scientific independence - a hallmark of any functioning democracy.

Looking forward to celebrating 80 years of federally funded science, technology and innovation @standupforscience.bsky.social SF, March 7, Civic Center, 1-3 pm 🧪 🧫 🧬

1/N. Why antiparticles exist (a thread)

the most surprising and disappointing aspect of becoming a global health philanthropist is the existence of an opposition team

Protecting the ocean has always been a bipartisan effort, in Congress and across multiple White House administrations. In the face of ill-conceived attacks on @noaa.gov, it's time to raise our voices. My thoughts in defense of NOAA and #OceanScience: mbayaq.co/4k8vEsx

For decades, the US government has painstakingly kept American science #1 globally—and every facet of American life has improved because of it. The internet? Flu shot? Ozempic? All grew out of federally-funded research. Now all that's being dismantled. 1/ www.technologyreview.com/2025/02/21/1...

The gap between the claims made in the Microsoft press release and the claims made in the actual paper are pretty astounding. From their own paper "These measurements do not, by themselves, determine whether the low-energy states detected by interferometry are topological." 5/

First paragraph of peer review file on recent Microsoft paper —

I’m in England, in a field of Barley. Today, I’m going to collect wild yeast under that tree back there, and I’m going to show how to feed and grow it until it’s ready to bake with. We are going to start at the very beginning, and end at the end. (this is an experiment in thread transfer)

The spikes you see coming out of stars in telescopic images mostly arise from the diffraction of light as it flows past the support arms that hold the secondary mirror in place. Diffraction is well understood, so which kind of support arms leads to which pattern is predictable. (I made this pic)

Was looking up some old work by Marc Levenson and Shelby after a long meeting with Marty Fejer and students ... and I stumbled upon this: doi.org/10.1016/0030... Have y'all (especially @johannesfink.bsky.social @mankei-tsang.bsky.social) seen this paper?

In the latest development in the raw milk saga, X is now unpasteurized.

Thanks Victor! (Also @mickeykats.bsky.social )

Happy New Year! I’m looking for a postdoc to join our new lab at UC Berkeley starting in summer 2025 (flexible). We are building Hybrid quantum systems based on neutral atoms platform with nanophotonics and superconducting circuits. ⚛️⚡️❄️ suleymanzadelab.com
