The development of quantum networks (QNs) relies on efficient mechanisms for distributing entanglement among multiple quantum users (QUs) under practical system constraints. This paper investigates the problem of entanglement rate maximization in a d...
Co-Authoring with AI: How I Wrote a Physics Paper About AI, Using AI
Yi Zhou·Apr 5, 2026
The rapid integration of Large Language Models (LLMs) into scientific writing fundamentally challenges traditional definitions of authorship, responsibility, and scientific integrity. As researchers transition from using computers as deterministic to...
Entanglement generation from gravitationally produced massless vector particles during inflation
Alessio Belfiglio, Mattia Dubbini, Orlando Luongo·Apr 4, 2026
We study the gravitational production of spectator massless vector particles in a single-field inflationary scenario, and the related entanglement generation across the Hubble horizon. Accordingly, we consider a quasi-de Sitter background evolution, ...
