Quantum Theory of Distributed-Feedback Parametric Amplifiers and Oscillators
Alex O. C. Davis, Alex I. Flint·Sep 6, 2025
Optical parametric oscillators are among the best-developed quantum light sources, having already been adopted in precision measurement and underpinning various quantum computing and communication paradigms. Meanwhile, progress in photonic structures...
Geometric Discord of any arbitrary dimensional bipartite system and its application in quantum key distribution
Rashi Jain, Satyabrata Adhikari·Sep 5, 2025
Entangled quantum states are regarded as a key resource in quantum key distribution (QKD) protocols. However, quantum correlations, other than entanglement can also play a significant role in the QKD protocols. In this work, we will focus on one such...
Quantum-inspired dynamical models on quantum and classical annealers
Philipp Hanussek, Jakub Pawłowski, Zakaria Mzaouali +1 more·Sep 4, 2025
We propose a practical, physics-inspired benchmarking suite to challenge both quantum and classical computers by mapping real-time quantum dynamics to a common optimization format. Using a parallel-in-time encoding, we convert the real-time propagato...
Quantum-Assisted Correlation Clustering
A. Macaluso, Supreeth Mysore Venkatesh, Diego Arenas +2 more·Sep 3, 2025
This work introduces a hybrid quantum-classical method to correlation clustering, a graph-based unsupervised learning task that seeks to partition the nodes in a graph based on pairwise agreement and disagreement. In particular, we adapt GCS-Q [1], a...
Exponentially Enhanced Tripartite Coupling in Quantum Nonlinear Magnonics
Xue-Chun Chen, Zi-Jie Wang, Sheng-Bo Zheng +2 more·Sep 2, 2025
Strong and controllable tripartite interactions play a pivotal role in quantum information and nonlinear quantum optics, yet challenging to realize. In this work, we propose a hybrid system consisting of a nitrogen-vacancy (NV) center coupled to Kerr...
