arXiv:2604.11952v1 Announce Type: new Abstract: Complexity class containments involving interactive proof classes are famously nonrelativizing: although $\mathsf{IP} = \mathsf{PSPACE}$, Fortnow and Si…
arXiv:2604.11910v1 Announce Type: new Abstract: Quantum correlations in networks with independent sources have revealed novel forms of nonclassical behavior. While entanglement in the sources is a nec…
arXiv:2604.11900v1 Announce Type: new Abstract: Programmable quantum hardware provides an emerging platform for exploring and controlling non-unitary quantum dynamics through measurement-based operati…
arXiv:2604.11897v1 Announce Type: new Abstract: We calculate the response of an Unruh--DeWitt detector in a 2+1d spacetime that contains a BTZ black hole in a superposition of locations. Upon performi…
arXiv:2604.11878v1 Announce Type: new Abstract: Processes with indefinite causal order (ICO), such as the quantum switch, are an emerging resource for quantum tasks and a fundamental test bed for stud…
arXiv:2604.11876v1 Announce Type: new Abstract: Closed chaotic quantum systems relax after a quench into a Gibbs ensemble. At late times, the relaxation speed is determined by their conservation laws …
arXiv:2604.11872v1 Announce Type: new Abstract: We provide a pedagogical introduction to eigenstate thermalization. This phenomenon, which occurs in generic systems, allows one to understand why therm…
arXiv:2604.11864v1 Announce Type: new Abstract: We present a parametrization of density matrices (mixed states) in a finite-dimensional Hilbert space $\mathbb{C}^n$, particularly suited to the descrip…
arXiv:2604.11858v1 Announce Type: new Abstract: We consider symmetries and reduction in non-relativistic many-body quantum mechanics, with the aim of identifying physically meaningful observables in s…
arXiv:2604.11857v1 Announce Type: new Abstract: Catalytic quantum error correction (CQEC) recovers quantum states via catalytic covariant transformations but requires full knowledge of the target stat…
arXiv:2604.11831v1 Announce Type: new Abstract: In hybrid classical-quantum computing, variational quantum algorithms (VQAs) have emerged as a promising approach in the Noisy Intermediate-Scale Quantu…
arXiv:2604.11830v1 Announce Type: new Abstract: Some skeptical arguments on the physical reality of quantum states are given. First, I argue that the algebraic formalism of quantum field theory in cur…
arXiv:2604.11825v1 Announce Type: new Abstract: Many nonlinear PDEs have singular or oscillatory solutions or may exhibit physical instabilities or uncertainties. This requires a suitable concept of p…
arXiv:2604.11823v1 Announce Type: new Abstract: According to various no-go results in the foundations of quantum mechanics, for any system associated to a Hilbert space of dimension higher than two, i…
arXiv:2604.11817v1 Announce Type: new Abstract: Hybrid quantum-classical models offer a promising route for learning from complex data; however, their application to multi-band remote sensing imagery …
arXiv:2604.11814v1 Announce Type: new Abstract: Quantum mechanics owes much of its extraordinary success to a Hilbertian program of mathematical formalization. Yet, the formalism remains poorly aligne…
arXiv:2604.12229v1 Announce Type: new Abstract: Small language models (SLMs) often struggle with complex mathematical reasoning due to limited capacity to maintain long chains of intermediate steps an…
arXiv:2604.12227v1 Announce Type: new Abstract: Student responses in STEM assessments are often handwritten and combine symbolic expressions, calculations, and diagrams, creating substantial variation…
arXiv:2604.12213v1 Announce Type: new Abstract: Preserving multimodal signals across agent boundaries is necessary for accurate cross-modal reasoning, but it is not sufficient. We show that modality-n…
arXiv:2604.12210v1 Announce Type: new Abstract: Simulating Standardized Patients with cognitive impairment offers a scalable and ethical solution for clinical training. However, existing methods rely …
arXiv:2604.12202v1 Announce Type: new Abstract: This study leverages large-scale travel surveys for over 200,000 residents across Boston, Chicago, Hong Kong, London, and Sao Paulo. With rich individua…
arXiv:2604.12191v1 Announce Type: new Abstract: Current evaluations of large language models aggregate performance across diverse tasks into single scores. This obscures fine-grained ability variation…
arXiv:2604.12184v1 Announce Type: new Abstract: TRUST Agents is a collaborative multi-agent framework for explainable fact verification and fake news detection. Rather than treating verification as a …
arXiv:2604.12177v1 Announce Type: new Abstract: LLM-based agents can execute actions that are syntactically valid, user-sanctioned, and semantically appropriate, yet still violate organizational polic…
