A nonlinear quantum neural network framework for entanglement engineering
Adriano Macarone-Palmieri, Alberto Ferrara, Rosario Lo Franco·Dec 16, 2025
Multipartite entanglement is a crucial resource for quantum technologies; however, its scalable generation in noisy quantum devices remains a significant challenge. Here, we propose a low-depth quantum neural network architecture with linear scaling,...
Fundamental bound on entanglement generation between interacting Rydberg atoms
Georgios Doultsinos, Antonis Delakouras, David Petrosyan·Dec 15, 2025
We analytically derive the fundamental lower bound for the preparation fidelity of a maximally-entangled (Bell) state of two atoms involving Rydberg-state interactions. This bound represents the minimum achievable error $E \geq ( 1 + π/2 ) Γ/B$ due t...
Distillation of continuous variable qudits from single photon sources: A cascaded approach
Devibala Esakkimuthu, Basherrudin Mahmud Ahmed Abduljaffer·Dec 15, 2025
Creation of high fidelity photonic quantum states in the continuous variable regime is indispensable for the implementation of quantum technologies universally. However, this is a challenging task as it requires higher nonlinearity or larger Fock sta...
High-purity frequency-degenerate photon pair generation via cascaded SFG/SPDC in thin film lithium niobate
Olivia Hefti, Marco Clementi, Enrico Melani +12 more·Dec 15, 2025
Frequency-degenerate photon pairs generated using nonlinear photonic integrated devices are a crucial resource for scalable quantum information processing and metrology. However, their realization is hindered by unwanted parametric processes occurrin...
Intense-Laser Nondipole-Induced Symmetry Breaking in Solids
Asger Weeth, Lars Bojer Madsen·Dec 15, 2025
High-harmonic spectroscopy in solids gives insight into the inner workings of solids, such as reconstructing band structures or probing the topological phase of materials. High-harmonic generation (HHG) is a highly non-linear phenomena and simulation...
Imaging Walk-Off Driven Distortions in EPR Photon Pair Correlations
Christian Howard, Roohollah Ghobadi, Nazanin Dehghan +2 more·Dec 13, 2025
Spontaneous parametric down-conversion is the primary source of position-correlated and momentum-anticorrelated photon pairs that form the canonical Einstein-Podolsky-Rosen (EPR) state. Their transverse spatial correlations are usually analyzed withi...
Mage: Cracking Elliptic Curve Cryptography with Cross-Axis Transformers
