Presentation titles and summary

• [P1] Alvaro Alhambra: "Introduction to Cluster Expansions, applications and open questions". This talk will cover the basics of cluster expansions and their applications, with a focus on long-range interactions.
• [P2] Martin Kliesch: "Stability of classical shadows under gate-dependent noise" [arxiv:2310.19947]. This presentation explores the impact of noise on classical shadows.
• [P3] Daniel Stilck França: "Hamiltonian Learning and Polynomial Interpolation". Daniel will discuss challenges and improvements in Hamiltonian learning for long-range systems.
• [P4] Tim Möbus: "Bosonic Information-Propagation Bounds with Applications in Hamiltonian Learning". Tim will address the challenges of bosonic systems and extend the results to these systems.
• [P5] Angela Capel: "Conditional independence of 1D Gibbs states with applications to efficient learning". Angela's talk will focus on efficient learning of Gibbs states in 1D and potential extensions to other settings.
• [P6] Michał Oszmaniec: "From POVM simulation to efficient circuit knitting" [arxiv:2104.05612]. Michał will discuss the POVM simulation protocol and its applications to circuit knitting.
