High-frequency backreaction for the Einstein equations under $\mathbb U(1)$ symmetry: from Einstein-dust to Einstein-Vlasov
Given suitable small, localized, $\mathbb U(1)$-symmetric solutions to the Einstein-massless Vlasov system in an elliptic gauge, we prove that they can be approximated by high-frequency vacuum spacetimes. This extends previous constructions where the limiting spacetime solves the Einstein-(multiple) null dust system (i.e., where the limiting massless Vlasov field can be written as a finite sum of delta measures). The proof proceeds by first approximating solutions to the Einstein-massless Vlaso…

Encoding molecular structures in quantum machine learning
Quantum machine learning (QML) has great potential for the analysis of chemical datasets. However, conventional quantum data-encoding schemes, such as fingerprint encoding, are generally unfeasible for the accurate representation of chemical moieties in such datasets. In this contribution, we introduce the quantum molecular structure encoding (QMSE) scheme, which encodes the molecular bond orders and interatomic couplings expressed as a hybrid Coulomb-adjacency matrix, directly as one- and two-…

You know, “this” used to be a perfectly innocent word. Nothing special, but a solid citizen of the grammar ecosystem. Who could have predicted it would turn into a major clickbait villain, meaning “We’re not going to tell you what this article is about until you click on it.”
FWIW I think I’m not alone in consciously avoiding clicking on such links.

Efficient LCU block encodings through Dicke states preparation
As algorithmic tools exemplified by the Quantum Singular Value Transformation (QSVT) continue to emerge as a unifying framework for diverse quantum speedups, the efficient construction of block encodings--their fundamental input model--becomes increasingly crucial. However, devising explicit block encoding circuits remains a well-recognized and challenging problem. One of the most widely studied and versatile approaches to block encoding is the Linear Combination of Unitaries (LCU). Despite its…
