Today I learned that the measurement problem had a satisfactory interpretation since 2002 within quantum statistical mechanics and WHY THE HELL NOBODY TOLD ME EVER

This reads like a movie script, props to Vincent for sticking to his guns despite the hierarchy.

Further unreliable research from @qutech.bsky.social and @msftresearch.bsky.social covered by @averyorrall.bsky.social from @retractionwatch.com. I shared details which I wanted to share within a confidential investigation of @tudelft.nl but it was shut down... www.science.org/content/arti... 1/n

Another new paper from our group: *Clifford and Non-Clifford Splitting in Quantum Circuits: Applications and ZX-Calculus Detection Procedure* We introduce compilation procedure using the ZX-Calculus to identify Clifford and non-clifford borders in quantum circuits. arxiv.org/abs/2504.16004

Clifford and Non-Clifford Splitting in Quantum Circuits: Applications and ZX-Calculus Detection Procedure

Classical simulation of quantum circuits is a pivotal part of the quantum computing landscape, specially within the NISQ era, where the constraints imposed by available hardware are unavoidable. The G...

This is our first paper in a series of two, which tackles the question of trainability of shallow QAOA algorithms. We provide benchmarks for quasi-newton and natural gradient methods, in addition to introducing a simple secant-penalization in BFGS updates [1/2] www.arxiv.org/abs/2504.16518

Preconditioning Natural and Second Order Gradient Descent in Quantum Optimization: A Performance Benchmark

The optimization of parametric quantum circuits is technically hindered by three major obstacles: the non-convex nature of the objective function, noisy gradient evaluations, and the presence of barre...

This is a bit of a personal admission: I thought for around one year that LiDAR systems were named after prof. Daniel Lidar. There I said it.

Have you ever wondered why diffusion models memorize and all initializations lead to the same training sample? As we show, this is because like in dynamic systems, the memorized sample acts as an attractor and a corresponding attraction basin is formed in the denoising trajectory.

PRIF and TU Darmstadt are hiring for cross-disciplinary positions for PhD and postdocs in arms control, mainly in nuclear engineering. RB appreciated ! www.cntrarmscontrol.org/news/snd-vac...

If the universe started out in a pure quantum state, how is anything in a mixed state now?

Hey #Quantumsky 👋🏾 This is an attempt at indexing the growing quantum community here on Bluesky. Please let me know if you'd like to be added to the list. Genuinely happy to see what looks like a successful migration from the birdsite 😄 go.bsky.app/VHXg1yi
