Are you a student or early-career researcher in quantum computing or quantum information? Then the following is for you. We're organising a focused, community-driven conference at Leibniz Universität Hannover, hosted by Prof. Robert Raussendorf. 🗓️ Save the date: August 27–29, 2025

On July 17-18 a small symposium "Dreams of Quantum" will be held in honor of David DiVincenzo's work and retirement at RWTH Aachen. The event can be attended via Zoom by all. Information about the program of speakers & the Zoom link can be found at www.quantuminfo.physik.rwth-aachen.de/cms/~bmmwed

Some statistical features of Haar unitaries can be well approximated in log depth, exponentially faster than previously thought. We give evidence that this is a 'truly quantum' effect by deriving linear lower bounds for orthogonal, Clifford, symplectic, matchgate groups scirate.com/arxiv/2506.2...

Happy birthday to this great place for science! And cheers to everyone currently staying there :)

8th International Conference for Young Quantum Information Scientists www.quantiki.org/conference/8...

There is now an official announcement: The TIB has archived the current status of the arXiv: blog.tib.eu/2025/05/14/p...

I'm hiring a postdoc! If you'd like to work with me on quantum learning, error correction, quantum algorithms, and FTQC at Virginia Tech in the Washington, DC metro area, please apply here: careers.pageuppeople.com/968/cw/en-us...

Fully-funded four-year PhD position on random circuits and shadows for many-body physics. Interested in working on fundamental problems and take it all the way to applications? Join my new team at U Cologne and Matteo Rizzi's group at FZ Jülich! Deadline: 18 May www.fz-juelich.de/de/karriere/...

We provide an efficient method to engineer arbitrary many-body Hamiltonians also robust against various dominant errors. I will present these results next Wednesday at #QCTIP2025. arxiv.org/abs/2410.19903

Encourage your organization to support arXiv. info.arxiv.org/about/fundin...

Bosonic Randomized Benchmarking with Passive Transformations journals.aps.org/prxquantum/a... We extend the popular randomized benchmarking (RB) protocol to bosonic systems, allowing to benchmark passive transformations using a small number of samples. Now in PRX Quantum!

Happy Pi day!!!

The registration deadline of the main event of the year on quantum computing theory in practice (#QCTiP2025) will be #tomorrow, anywhere on Earth. qctip2025.com

We provide a classical simulation of DWave quantum "s-word" paper. Here it is arxiv.org/abs/2503.08247 , great work by Linda Mauron at the CQS Lab, check it out! (1/4)

I have a positive update regarding this matter: The German National Library of Science and Technology in Hannover (TIB, www.tib.eu) confirmed that they will download and archive the entire arxiv.org as a safety measure.

PhD position on sample-efficient quantum gate calibration at FZ Jülich @fz-juelich.de, jointly supervised by Prof. Dr. Felix Motzoi (PGI-8) and Dr. Markus Heinrich (University of Cologne @unicologne.bsky.social). #QuantumComputing www.quantiki.org/position/phd...

FZ Jülich is hiring a PhD candidate which will be co-supervised by myself at U Cologne. Interested in benchmarking/characterisation, in working in a highly collaborative environment, and want to see your work being used in experiments? Consider applying! www.fz-juelich.de/en/careers/j...

Our paper on the robustness of classical shadows under gate-dependent noise has been published in PRL! Many thanks to my great collaborators Raphael Brieger, Ingo Roth, and Martin Kliesch! journals.aps.org/prl/abstract...

Thanks @zlatko-minev.bsky.social and hello bluesky world!

Happy to see that our paper on Efficient Hamiltonian Engineering (arxiv.org/abs/2410.19903) was accepted as a talk at QCTiP! Stay tuned for a major update, including robustness results for our method, during the next few weeks!

I think it would be a good time to reinstantiate the mirror network for the # arXiv. It’s an essential piece of the global research community in math, physics, computer-science and adjacent fields. Under the current circumstances it should not only be hosted in the US. #quantum #math #physics #cs

Our sixth and final long plenary is a merged talk featuring two presentations. Details and overview below! @felixled.bsky.social

Hello world! The quantum journal is now on BlueSky!

🎬… and cut. We are done recording lectures for my course “Quantum Computational Physics”. Tune in if you want to do “quantum on quantum”: concepts, algorithms, and practical computational skills to simulate quantum many-body systems on digital quantum computing platforms. vimeo.com/showcase/Qua...

Wozu ein Quantenjahr? Braucht die Quantentechnologie mehr Aufmerksamkeit und noch mehr Hype? 💡 Ganz im Gegenteil. Wir brauchen weniger Hype und mehr Verständnis! Mehr dazu in meinem Editorial in der aktuellen @ct.de und online (free): www.heise.de/meinung/Komm...

Just a friendly reminder that applications to our summer school are open until January 19th 2025!! Apply here if you haven't: lanl-summer-school-programs.wizehive.app/program/quan... Or please complete your application by the 19th

The deadline for talk submissions at QCTiP 2025 is coming up! Consider submitting a talk until January 10.

Saw these climbing shoes on sale earlier… there’ll be articles on quantum bouldering before you know it

Here is the referee report for that paper. :) Same would apply here.

I'm hiring a postdoc to work with me at the University of Illinois Urbana-Champaign! For details and how to apply, visit felixleditzky.info/postdoc2024.... Applications received by January 10 (AoE) will receive full consideration. Please share!

Submissions for QCTiP 2025 are now open.

I totally agree! There are already some great questions and answers on QC SE, so please consider joining the site. Note that being curious and asking interesting questions is half the effort there!

I am turning this into a game: When was the first use of the name "Clifford group" for the normalizer of the Pauli group? The first one to give the right answer wins a free beer at the next QIP :-)

Just created a Quantum Computing Starter Pack. Please reach out if I missed to add you. go.bsky.app/KBgRwmZ

New paper alert! We investigate the stability of classical shadows under gate-dependent noise, in particular whether dimensional factors in the estimators can exponentially amplify small gate errors We show that for Clifford circuits, this cannot appear. scirate.com/arxiv/2310.1...
