I woke up this morning to see that @ccanonne.github.io has won a measly grant. Congrats! :)

Both stop work orders on my two grants have now been released. Unfortunately, the agency for one grant reallocated the funds, so likely those won't come back. This has gone on for seven months now, and there was no clear point to any of it. I am grateful to colleagues for stepping in to help out.

Joint work "Limiting one-way distillable secret key via privacy testing of extendible states" w/ Vishal Singh, Aby Philip, & Karol Horodecki now available: scirate.com/arxiv/2511.0... The paper establishes a fundamental bound on how well k-extendible states can pass the privacy test.

Physical Review has indicated in a paper proof that they have their own style for author contribution statements. This style consists of massacring our statement, by repeating "formal analysis" multiple times & unnecessarily capitalizing phrases. Why does APS consistently have such poor copyediting?

During Dec. 8-11, @wangxinfelix.bsky.social & I are co-organizing an online event called the International Workshop on Quantum Boltzmann Machines: wqbm.info

here is what I see when I want to look up research papers on @nature.com 's web site. Why do I need to see ads like this? really??? Do you not get enough money from charging authors exorbitant publication fees? This is really pathetic.

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 workshop Quantum Resources is back! The next edition will take place in Tokyo in March. 2026.quantumresources.science Submission deadline: 31 October 2025 Workshop: 16–20 March 2026

When you realize the whole yearly budget for Quantum journal is equal to 8 Nature APCs - and they don't even wreck your paper in proof stage because...there is none

Our research group is seeking a talented and motivated Postdoctoral Researcher to join us in advancing the practical realisation of quantum technologies (including quantum error correction and mitigation). The deadline is 06 October 2025: tinyurl.com/bdhf3hzt

187 total entries for quant-ph on a single day suggests it might be time to split up quant-ph into at least two separate categories: arxiv.org/list/quant-p...

Joint work with Kaiyuan Ji and Seth Lloyd now available at arxiv.org/abs/2509.08965 This paper identifies the communication capacity for sending information from the future to the past through a noisy closed timelike curve. The formula is reminiscent of mutual info but in general can be larger.

Fancy being (academic) neighbours? The University of Basel are hiring a tenure-track assistant professor in theoretical quantum computing: jobs.unibas.ch/offene-stell...

Also, sharing for friends: Anyone fancy a (minimal teaching load) tenure track position on quantum computing on a sunny island 🌤️ 🏝️? The Cyprus Institute are also hiring a tenure track assistant proff on quantum algorithms. onlinerecruitment.exelsyslive.com?c=6E7274A2-8... (Deadline next week)

Tomorrow will be Cornell Information Theory Day, with program available here: find.engineering.cornell.edu/cornell-info... Book of abstracts here: find.engineering.cornell.edu/files/2025/0...

Things would be a bit easier if the Oxford English dictionary could add the following words: infimization infimize supremization supremize I think mathematicians use these words regularly even though they are not official English words.

Joint work "Solving Optimal Power Flow using a Variational Quantum Approach" w/ Thinh Viet Le & Vassilis Kekatos: arxiv.org/abs/2509.00341 Optimal power flow (OPF) is an optimization problem central in the operation of electric power systems. We propose a variational q. paradigm for solving OPF.

Hi, I am here! Will mostly post about Quantum Foundations/Computing and Quantum Music.

My colleague's submission was rejected from QCRYPT, but he indicated that several people have been coming up to him during the lunch breaks to tell him how useful his result is and how they have been making use of it in their own work. Does that make up for the rejection? :)

Our CEO @jfitzsimons.bsky.social presented our unique approach to quantum programming at Q2B Silicon Valley 2024. This year’s Q2B will see us showcase further technical breakthroughs and progress towards building the most capable and easy-to-use tools to write complex programs for quantum hardware.

Quiz: Who is the scientist on the left whose name is well known in quantum information theory?

I'll be attending SQuInT 2025: squint.unm.edu/events/2025.... Anyone else on bsky planning to go? (out of curiousity)

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

My colleagues and I have issued an update of our paper: arxiv.org/abs/2412.02134 New title: Sample-based Hamiltonian and Lindbladian simulation: Non-asymptotic analysis of sample complexity Updated results summarized in attached table

Was fun to record a podcast for @intelligence2.bsky.social with the wonderful host Shini Somara on our book "Why nobody understands quantum physics": scientists and writers, unite! open.spotify.com/episode/6sBG...

#IPAM (the institute for pure and applied mathematics) is facing a critical shortfall for operating expenses due to an unexpected suspension of NSF funding www.ipam.ucla.edu/news/nsf-fun... . Donations for emergency continuity of operations funding can be made at giving.ucla.edu/Campaign/Donat

I'm happy to see support for non-commutative algebra, which is very useful for Taylor expansions of Hamiltonians with non-commuting terms, such as in the Baker–Campbell–Hausdorff formula. en.wikipedia.org/wiki/Baker%E... Sometimes I had to implement this by hand, so it's nice to have it built in.

Terence Tao (@teorth.bsky.social) has written a thread on Mastodon about the impact of the federal grant freeze to UCLA, particularly to his own field of Mathematics. UCLA's IPAM (Institute of Pure and Applied Mathematics) could shut down entirely mathstodon.xyz/@tao/1149568...

Today is Cornell Quantum Day: quantum.cornell.edu/cornell-quan... We have a schedule of external and student speakers lined up, with a blend of theory and experiment

from scirate.com/arxiv/2502.0... : "our proposed algorithm can be interpreted as a tâtonnement dynamic" It is always a good strategy in academia to use technical terms that no one else knows, in order to pique the curiosity of readers

It took Quantum Journal three months and two reminders to invite reviewers for my submission there. Within one hour of receiving the invitation to review, the invited reviewers confirmed. To stay relevant, Quantum Journal will certainly need to improve significantly in this regard.

Ian George, @christophhirche.bsky.social, Theshani Nuradha, & I have issued an update of our q. Doeblin coefficients paper: arxiv.org/abs/2503.22823 Main changes consist of an expanded section 8.5 on mixing, indistinguishability, & decoupling times of quantum Markov chains. See attached images

I am curious about QI people who use LyX to help write their research papers and math notes. I noticed @quantum-journal.bsky.social has a LyX template, which suggests the # of people using it is sizable. Please reply here if you do. I recently switched from Scientific Workplace to LyX & am impressed

Theshani Nuradha & I issued an important update of our paper on query complexity of q. channel discrimination: arxiv.org/abs/2504.12989 Building on arxiv.org/abs/2506.13686, we gave a tight characterization of sample complexity of state discrimination & query complexity of cq channels. See images

I posted my slides on resource theory of asymmetric distinguishability: zenodo.org/records/1577... Joint work w/ @wangxinfelix.bsky.social from 2019 & came up in discussions at #ISIT2025. This work gave the first proper operational interpretation for smooth max-relative entropy

RIP Ray Laflamme, gone too soon. Ray was a stellar scientist, the founding director of ⁦‪the IQC‬⁩ and ⁦‪of CIFAR's‬⁩ Quantum Information program, but more importantly a warm & generous human who built community and helped many (particularly junior researchers). May his memory be a blessing.
