Our paper elucidating resources required for quantum Gibbs state preparation via Lindblad simulation is now published in @quantum-journal.bsky.social quantum-journal.org/papers/q-202...

🧵 1/? Today #quantinuum announced Guppy, the new programming language my team has been developing, and Selene the new simulator that goes with it. This is the software stack that supports our new Helios #quantum computer, and it successors. #quantumcomputing www.quantinuum.com/blog/built-f...

Our latest paper is out. In a joint work with Marcello Benedetti and Matthias Rosenkranz ( @mrosenkranz.bsky.social ) , we present a new quantum algorithm for solving Lyapunov equations. scirate.com/arxiv/2508.0... arxiv.org/abs/2508.04689

We have an opening for a research scientist in the quantum algorithms team at Quantinuum. This is permanent in London or Cambridge, UK. Details: jobs.eu.lever.co/quantinuum/2...

What's this? Some very nice work by my colleagues. #quantinuum #quantumcomputing #ftqc #quantum arxiv.org/abs/2505.09133

Happy that our paper on state preparation for multivariate functions is out in @quantum-journal.bsky.social. We've also open sourced the code. Give it a go in your algorithm: github.com/CQCL/mvsp

Hi #quantum bluesky 👋 In arxiv.org/abs/2503.20870 with #Quantinuum, Fermioniq, Caltech, EPFL, TUM we show Quantinuum's H2 ion-trap #quantumcomputer can simulate dynamical evolution of a 2D Ising model at late times and sizes pushing beyond classical means(MPS, PEPS, sparse Pauli propagation, NN).

Here's one from our algorithms team and QuSoft/CWI

If you’re running randomized benchmarking on your quantum computer, stop and read our paper! arxiv.org/pdf/2502.00154

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

Very happy that our new paper on quantum Gibbs state preparation is out today 🎅 scirate.com/arxiv/2412.1... We hope this bridges the gap between the recent theoretical advances in Lindblad simulation algorithms for quantum Gibbs sampling and their eventual quantum hardware implementation.

Interesting question by Mark Wilde on Twitter: There have been many breakthrough algorithms for thermal state preparation recently. Does any of them prepare a canonical purification of a thermal state? i.e, the following state (\sqrt{e^{-H}/Z} ⊗ I) ∑_i |i⟩ ⊗ |i⟩ with |i⟩ = computational basis

Submissions for QCTiP 2025 are now open.

it will be interesting to see whether this "classical attack" gives anything for the "optimization by decoded quantum interferometry" paper arxiv.org/abs/2408.08292

The plot thickens: "While all the proofs in the paper are correct to the best of our knowledge, we have been recently informed about a classical attack on our polynomial system."

So close! Somebody please post something really good 🙏

Happy No arXiv Announcements Day to those who celebrate
