I recently submitted my PhD thesis 🎉 I am now planning the next step of my journey. I will stay in Berlin for personal reasons, which makes me curious which research groups and companies would hire postdocs or equivalent for remote positions. If you have any leads, please DM!

Check out our published paper and Marco's thread below! One thing to appreciate about ML as an application for quantum computers is that cheap, truncated simulations are themselves valid models. Beating them with shot noise and daunting gradient scaling is no easy feat.

Extremely proud to see our paper "Quantum Convolutional Neural Networks are Effectively Classically Simulable" published in PRX Quantum journals.aps.org/prxquantum/a... This is an instantiation of our work, provable absence of barren plateaus implies classical simulability.

Hey - we've extended Pauli and Majorana propagation to simulating thermal states The trick is to imaginary-time evolve identity and then normalize by the trace of the Pauli (or Majorana) sum at the end The catch is that both our analytics and numerics suggest it only works at high temperatures 🧵👇

Did you know you can simulate quantum states with Pauli and Majorana propagation? In short: High-temperature states are provably and practically sparse, and we can use imaginary time evolution to get there starting from the infinite-temperature state. scirate.com/arxiv/2602.0...

Happy to share our paper: Leveraging Symmetry Merging in Pauli Propagation scirate.com/arxiv/2512.1... tl;dr We improve standard Pauli propagation by merging Pauli strings related by symmetry. Shoutout to my collaborators @sueyeonchung.bsky.social @quantummanuel.bsky.social @qzoeholmes.bsky.social

I am so, so happy to see this article published as a perspective in Nature Communications: www.nature.com/articles/s41... More than the paper itself, I thoroughly enjoyed chatting with all my co-authors on the implications of the absence of BPs ~ classical simulability connection

There has been growing evidence that strategies to circumvent the barren plateau problem in variational quantum computing might also kill potential quantum advantages. In this Perspective, the authors...

Welcoming summer the best way we know how: with pasta, physics, and a phenomenal team 🍝⚛️ A warm #Google #Quantum #AI welcome to Manuel Rudolph, who’s joining us this summer! 🎉 We’re thrilled to have his sharp mind and curious spirit with us Thx Nikita+team for organizing

In case you thought you can't efficiently simulate and sample quantum circuits with 2D tensor networks... Nope, you can. Link: scirate.com/arxiv/2507.1... We simulate IBM's recent quantum chemistry experiments and Williow + heavy-hex Heisenberg dynamics, and showcase modern, verifiable techniques.

Last week, we published a paper that really excites me: "Circuit compression for 2D quantum dynamics" Using Pauli propagation, we (Matteo) were able to compress Trotter circuits for systems up to 30x30 with depth reductions of x2 to x13. Link: arxiv.org/abs/2507.01883

Retweeting this for the folks (myself included) that weren't online over the long weekend PauliPropagation.jl is open source library that you can use to approximately simulate quantum circuits We explain the nitty gritty of how these algorithms work in practise in our latest companion paper 🧵👇

UnitaryHACK 2025 has begun - and we are part of it! If you are registered, earn real money by closing GitHub issues in our new library PauliPropagation.jl (github.com/MSRudolph/PauliPropagation.jl). We were supposed to have a nice and "compact" paper out today, but the arXiv gods were not with us.

I'm heading to APS for the week. If you are around, let me know! Or say Hi after my talk in the C34 session on Monday afternoon.

Oh no, tensor networks have out-supremed D-Wave!

In a new preprint arxiv.org/abs/2503.05693, led by Joseph Tindall and Antonio Mello at Flatiron CCQ, we simulate annealing of disordered quantum magnets 🧲 ⌛ and in many cases find better accuracy than recent results from D-Wave devices and leading classical methods (c.f. arxiv.org/abs/2403.00910).

Here we take steps to understanding the potential of warm starts for VQAs We provide a general variance lower bound for patches of loss landscapes: - for both structured and unstructured circuits - to provide small-angle-initialization 'guarantees' - to study the scaling of regions of attraction

Ricard Puig@pvricard.bsky.social · last yr.

New paper on arXiv 🔥 We present a bound that unifies all the previous guarantees of small regions with substantial gradients in BP landscapes. This allows us to study new architectures, parameter correlations, and points on the landscape that could not be analyzed before. scirate.com/arxiv/2502.0...

In the spirit of friendly academic shit posting... (Or because we lack imagination?) We picked another IBM experiment to benchmark our small-angle Pauli propagation alg. This time: arxiv.org/abs/2404.08053 @quantummanuel.bsky.social's plot below is for TFI on 127 qubits in a heavy hex topology

Out today, our latest paper on the theme of: "offload as much work as possible from NISQ hardware" Here we focus on classically simulating small regions ("patches") of an expectation landscape Our algs/theorems apply to dynamical simulation, VQAs and beyond ➡️ scirate.com/arxiv/2411.1... ⬅️ 🧵👇

Kicking off my existence on this platform with a paper release 🔥 We propose a framework for the quantum-enhanced classical simulation of small expectation landscape "patches". In short: You can do more classically than you might have thought. scirate.com/arxiv/2411.1... #quantum
