Sometimes work takes you to Fayetteville #hotelview

I gave a talk about our quantum error correction tools at the Monte Verita Quantum Codes conference. It has been a great conference so far including experiment and theory for both CV and DV codes.

We just posted a new paper: “Architecting Early Fault Tolerant Neutral Atoms Systems with Quantum Advantage” arxiv.org/abs/2604.19735 🚀🎉 Our goal was to identify fault-tolerant (FT) architectures for neutral atom platforms that can enable quantum advantage experiments in the near future.

Accepted submissions for QEC26 are out: qec-conference.org/2026/accepte.... Congratulations! If you are attending QEC, a few reminders below:

Congrats to Keegan Ryan for being the first to exploit the simulator we used to validate the secret quantum circuits: blog.trailofbits.com/2026/04/17/w... It kills me that the (now fixed) bugs were simple (we didn't port the op validation code from C++ to Rust!), but that's to be expected.

In this MURI project with Sebastian Will (Columbia), Yongshan Ding (Yale), Shruti Puri (Yale), and Daniel Grier (UCSD), we will explore the potential uses and benefits (and limitations!) of using quantum gates that can act on many qubits at a time.

Swarnadeep Majumder, Brown Lab Alumni, at the APS Global Summit!

I'm looking forward to the Kavli Symposium tomorrow at the APS Global Physics Summit, where I'll speak about "The Road to Quantum Advantage." summit.aps.org/events/MAR-X02

Wow, amazing!! www.quantamagazine.org/quantum-cryp...

To close out the first day, I'm in a session where Michael Turner and Maria Spiropulu are presenting the EPP report for the future of particle physics, which came out last year. (Separate from the '24 P5 report) EPP Report: www.nationalacademies.org/read/28839/c...

Dropping in to this session on changes to student visas. summit.aps.org/events/EVM-J...

On another note, I’m looking for a 6‑month intern to work with me. Feel free to reach out to me. #QuantumComputing #QuantumErrorMitigation #MachineLearning #APSSummit26 #QuantumResearch

Starting off Monday with the... well, memorial plenary for the Relativistic Heavy Ion Collider (RHIC).

Celebrate with us Quantum's approaching 10 year anniversary in 2026 with the publication of the 2026th paper! Do you know which paper that is? quantum-journal.org/2026-quantum...

The APS Meeting in Denver starts in earnest tomorrow and as sort of an experiment to see if this still works, I've resolved to actually cover the conference on social media (like we did in days of yore), so bear with me for what will be a couple days of posting about physics.

I am the #APSSummit26 (aka #MarchMeeting26 and #AprilMeeting26) and speaking at the session celebrating Abhinav Kandala being awarded the 2026 Landauer Bennett Award in Quantum Computing. If you are at the meeting, please join us on Tuesday summit.aps.org/events/MAR-G03

Had a great visit to the University of Wisconsin - Madison. Here is the #hotelview photo of the amazing new CS building, Morgridge Hall.

If you are interested in working in the intersection of QEC and software check out our job posting for a position at Quantinuum: jobs.eu.lever.co/quantinuum/b... Areas of research include QEC software development, logical noise modeling, resource estimation, QEC/Hardware co-design, and more.

Have you ever wondered about the dimensionality of the massive Schwinger model with a two-dimensional, non-periodic electric field? Well, we counted it and proved that it follows the bisection of the Lucas numbers (oeis.org/A005248). This leads to incompatibility with Gauss's law stabilizer QEC.

Registration is now open for QEC26, to be held this June in sunny Santa Barbara, CA! See the registration page at qec-conference.org for a link. Also, the deadline for submissions is next Friday. Make sure to get those in and spread the word to friends and collaborators!

10 years after its founding, driven by the energy, enthusiasm, & dedication of the community @quantum-journal.bsky.social quietly published paper #2000 some days ago. At least I think this is a big deal, big shout out to the founders & all authors, reviewers, editors, board members & contributors!

Excited to see Swapnil Patel's paper measuring charge exchange between K and CaH+ on the arXiv arxiv.org/abs/2602.09142 . Joint work with @michaltomza.bsky.social and Dibyendu Sardar at the University of Warsaw. Here is a picture of Swapnil (orange jacket) skiing with other Brown lab alumni.

The Call for Submissions for QEC26 is now up: qec-conference.org/2026/call/ Follow the link to submit your paper or poster by March 6th AOE.

The call for submissions is now live on the QEC website! Deadline is March 6th, AoE. Please consider submitting and we'd appreciate it if you spread the word! :)

Logical qubits encoded in the fusion space of non-Abelian anyons in a generalized surface code. Not the most efficient way to build a quantum computer, but definitely the coolest! Quantinuum and co show how it's done on one of their H2 devices. arxiv.org/abs/2601.20956

Great list from Dave. Also if you haven't visited the Museum of Jurassic Technologies you should.

post a perfect album from the 90s that isn't nirvana, pearl jam, etc etc

🎆As the year ends, I want to remind everyone that our summer school applications are open! Please apply/encourage your students to apply here: academicjobsonline.org/ajo/jobs/31108 We also have a handshake link too🤝 : app.joinhandshake.com/emp/jobs/105... Shares appreciated!

INTERNET makes your job easier, INTERNET gives your job to ROBOT, by me in 2015. If I drew it today, ROBOT would be AI.

Last stop in Korea the ICAMD conference in Busan. They had a booth to dress up in Joseon dynasty dress. Here I am dressed as a scholar.

Third stop on the Korea Tour was Seoul National University. I met with Prof. Taehyun Kim and his group. Here we are in the Yb+ lab.

Next stop on the Korea tour was Sungkyunkwan University. I met with Profs. Yonuk Chong, Junki Kim, Dongmoon Min, and Seok-hyung Lee. Here I am with Prof. Chog, Prof. Kim and Dr. Quantum.

First stop on Korea trip last week: Ewha University and the labs of Prof. Taeyoung Choi.

Great visit to Tufts a few weeks ago. They have an open-rank job in Quantum Information / Computing theory. Open Positions | Department of Physics and Astronomy share.google/NosuSUs77OZU...

QUITS now out in Quantum quantum-journal.org/papers/q-202...

Hi, #quantum researchers and authors! Some friendly, informal, totally non-binding advice from your Editor in Chief at IEEE Transactions on Quantum Engineering (TQE). #QuantumComputing #QuantumInternet 1/about a hundred

Nice collection @rdvquantum.bsky.social I really like "Coming of the Light" in Broken Stars.

🚀 We just posted a new paper on arXiv! “Dynamic local single-shot checks for the toric code” arxiv.org/abs/2511.20576

A few quick notes: 1) Magic - not my favorite word choice - comes from magic angle directions and into quantum computing by arxiv.org/abs/quant-ph... . It is not about entanglement.

If I believed in the simulation hypothesis (see en.wikipedia.org/wiki/Simulat... for my opinion that somehow made it to Wikipedia) I’d say this is obviously how magic works arxiv.org/abs/2511.15304

Congrats to Samuel Phiri for successfully defending his thesis!

Also my experience. Academic culture benefits immensely from terrific people at the top. To put it more bluntly "Dave Wineland is super nice. Why do you think you can be a <insert favorite expletive here for someone who is a pain to work with >?"

If you are interested in doing a postdoc with me, please apply to the IQC postdoctoral fellowship here: iqc-uwaterloo.slideroom.com#/login/progr...

A great example of the challenge of writing tests.

Aside from Yang-Mills theory and parity nonconservation, Yang made so many profound contributions to physics! One that deeply impressed me as I was starting grad school: a 1975 paper with T. T. Wu highlighting the role of fiber bundles in gauge theory. www.nytimes.com/2025/10/18/s...

A little treat going into the weekend: the midterm for my quantum mechanics class was a couple weeks ago, and again the students made memes for extra credit. Let's start out strong with a PSA about the dangers of nondegenerate perturbation theory. Do you know where your good states are?

Fault-tolerant logical measurement just got a lot faster! In new work, we show that code surgeries based on hypergraphs, rather than graphs, allow fast and parallel fault-tolerant logical measurements with low qubit overhead (without requiring the code to be single-shot). arxiv.org/abs/2510.14895
