Since last year's retreat was such a success, we again took to the mountains to talk physics, generate new ideas and hike a lot! mbqd.de/post/2022-grou…

Our work on localization in a spatially disordered, long-range interacting Heisenberg XXZ spin system got published in PRB! Here is a small blog with an overview of the results (and a bonus gif): mbqd.de/post/2022-pair… Paper: journals.aps.org/prb/abstract/1…

Happy to see our work published in MLST!

Which network architectures capture the properties of quantum systems optimally? We systematically compare different NQS ansatz functions on benchmark problems and identify the details of symmetrization as a key to better performance: arxiv.org/abs/2301.06788

We have used supervised learning to estimate entanglement entropy and quantum mutual information in spin chains using very few experimental samples. On top, the method also estimates the statistical error. Comments welcome! arxiv.org/abs/2309.07556

The Husimi Q distribution is a phase space representation of quantum states, just like the Wigner function, but it doesn't get negative. Still, it can be used to detect entanglement, with advantages for experiments with sparse data... journals.aps.org/prl/abstract/1…

And we are back from the group’s annual retreat, this time held in Rathen🌲We hiked, discussed physics and explored synergies💡Now it’s time to materialise our generated ideas back in Jena!

Yesterday Adrian Braemer successfully defended his PhD thesis, having worked on quantum thermalization and disordered spin systems. Congratulations! 🎉

📢Introducing a scalable & experiment-friendly readout error mitigation scheme. We combine overlapping detector tomography with hierarchical clustering, avoiding randomized measurement & entangling gates, & apply this to systems of up to 100 qubits. journals.aps.org/pra/abstract/1…

back from our annual group retreat in the mountains in Ehrwald, Austria 🌄 with no shortage of hiking, stunning views, as well as discussions on physics and ways to improve as a research group, it was an all-round success

💡new paper on PRA: we show how entanglement can be verified using only a separable coherent state as a reference state! 🔎our separability criteria can be accessed by using an interferometric setup and photon-number detection journals.aps.org/pra/abstract/1…

🚀we present a method to certify high-dimensional time-bin entanglement in fiber-loop systems, crucial for advancing QKD, that is: ✅noise-resilient ✅adaptable entanglement dimension ✅requires only two measurement bases & works with limited data journals.aps.org/pra/abstract/1…
