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

Here's the recording of my talk at the Simons institute quantum industry day: www.youtube.com/live/SULOaOQ... And the slides: docs.google.com/presentation... I was also on the panel discussion at the end of the day (also in the linked playlist).

After #SQuInT2025 concluded, @balintpato.bsky.social , Cole Maurer, & I opted for a post-conference discussion on quantum computing, its capabilities, public perception of it, and various geopolitical issues that have arisen recently. Recording available here: www.reverbnation.com/markwilde/so...

The pioneering work of Clarke, Devoret, and Martinis showed that very cold electrical circuits behave in ways that exhibit fundamental principles of quantum physics. www.nobelprize.org/prizes/physi...

Nice result on inherent size of fault-tolerance scirate.com/arxiv/2510.0... "Our work contributes to this broader effort by providing evidence of inherent limits: Even when codes have good rate, there may be fundamental constraints on how much they can reduce the volume of fault-tolerant circuits."

It may not be shiny but there are several critical enabling technologies needed to make quantum networking happen ⚛️ phys.org/news/2025-10...

Went to the Wintergreen Meeting on Physical Chemistry wintergreen.web.illinois.edu and had a nice hike with @juliebiteenlab.bsky.social

One danger of modern social media is that crazy posts, bot posts, and real posts all look professional due to formatting. I call it the myspace vs facebook divide or the difference between a zine and a pamphlet. Now I find this non-crazy zine on social media and may need to rework my analogies.

My favorite Robert Redford movie is Sneakers which features a computer that can break RSA encryption and came out 2 years before Shor's algorithm. www.youtube.com/watch?v=F5bA...

Tenure track assistant prof job up for grabs in Basel. It's quantum computing theory, based in computer science, and part of the NCCR SPIN. Whoever gets this job will probably have to collaborate with me. Whether you see that as a pro or con is up to you. jobs.unibas.ch/offene-stell...

New paper out ✨ Fault-tolerant Transformation of Spacetime Codes, a collaboration w/ @vasmer.bsky.social, Austin Daniel & Ilan Tzitrin, which started during my internship @xanaduai.bsky.social scirate.com/arxiv/2509.0... Let's now see if I can summarize 101 pages (🙈) in a few tweets (and memes!)

If you are a college student, maybe a week or two into the semester, why not visit office hours and ask your professor that question? You know, that thing you were wondering in class? Or when you were doing the homework? Go ask them! That’s why they are there. They will be excited to see you.

In 2019 Rob Thew (www.unige.ch/gap/qic/qtec...) and I hosted a Workshop on US-EU Collaboration in Quantum Information Science at the @optica.org building. Here is the workshop photo. I know @tahantech.bsky.social and @andreasateth.bsky.social are on bluesky. Everyone else tag yourself.

We had 4 posters at QEC 2025. Eren's poster received an Honorable Mention in the poster competition. Congrats to Eren!

It's been an amazing week at QEC25 seeing the incredible work people have done in the field over the past couple of years! Abe Jacob did a fantastic job presenting our new work on trivariate tricycle codes, quantum LDPC codes that combine several nice fault-tolerant properties.

Consider this being told n+1 times.

EPiQC was an NSF Expedition project led by Fred Chong at the University of Chicago. We had a mini-reunion at QEC2025

Here is what we did this summer: arxiv.org/abs/2508.09103 All students in attached image are in 1st year undergrad or high school. Due to frozen funds, some volunteered & others were funded by Cornell Engineering. Thanks for your dedication & thx to other coauthors for helping to complete the work

If you saw my talk yesterday at QEC, this paper is the one that allows us to further improve distance of the mid cycle states further!

I’m not at QEC25, but I’m still learning decoding things from @dabacon.tachyon.institute at the UW seminar

@andreasateth.bsky.social and I exchange pullovers at QEC2025

Very exciting announcement, the next Quantum Error Correction conference QEC26 will be hosted by Google 7-12 June 2026 in Santa Barbara. See you there! @dripto.bsky.social @mattmcewen.bsky.social

My friend who worked for CISCO said "The key to flying all the time is a hard-shell carry-on bag that fits in a CRJ-900 overhead bin." My second suit case that followed her advice reached its end.

The infectious enthusiasm of my wonderful co-authors (Robert Huang, Soonwon Choi, Jarrod McClean) drove this upbeat assessment of “The Vast World of Quantum Advantage.” arxiv.org/abs/2508.05720

🎉 Congratulations to @aspuru.bsky.social on receiving the Heinrich Emanuel Merck Award for Computational Sciences! He was recognized for pioneering work at the intersection of quantum computing, AI, automation and chemistry. More details here: www.utoronto.ca/celebrates/a...

@mjbiercuk.bsky.social and Q-CTRL helping out the #qec2025 conference with performance boosters.

A second Quantum paper within three weeks! We show how to construct a class of qubit "Evenbly codes" - toy models of holography at finite N - which turn out to be highly tunable subsystem codes that can be made resilient against different types of quantum noise. Why "Far from Perfect"? Well...

In our world of (noisy) data, error correction is everywhere, as Mary Wootters eloquently explains. www.quantamagazine.org/how-can-math...
