Quantum Key Distribution: Bridging Theoretical Security Proofs, Practical Attacks, and Error Correction for Quantum-Augmented Networks
Nitin Jha, Abhishek Parakh, Mahadevan Subramaniam·Nov 25, 2025
Quantum Key Distribution (QKD) is revolutionizing cryptography by promising information-theoretic security through the immutable laws of quantum mechanics. Yet, the challenge of transforming these idealized security models into practical, resilient s...
Proximity driven photon-tunneling in chiral quantum hybrid systems
Aryan Pratap Srivastava, Moulik Deviprasad Ketkar, Kuldeep Kumar Shrivastava +3 more·Nov 25, 2025
We investigate photon tunneling in a pair of coupled inverted circular split-ring microwave resonators with four discrete chiral orientations. By varying the spacing between the resonators, we observe strong modulation of the transmission spectra, in...
Quantum Framework for Wavelet Shrinkage
Brani Vidakovic·Nov 25, 2025
This paper develops a unified framework for quantum wavelet shrinkage, extending classical denoising ideas into the quantum domain. Shrinkage is interpreted as a completely positive trace-preserving process, so attenuation of coefficients is carried ...
Quantum Coherence of Rare-Earth Ions in Heterogeneous Photonic Interfaces
Henry C. Hammer, Hassan A. Bukhari, Yogendra Limbu +6 more·Nov 24, 2025
Harnessing rare-earth ions in oxides for quantum networks requires integration with bright emitters in III-V semiconductors, but local disorder and interfacial noise limit their optical coherence. Here, we investigate the microscopic origins of the e...
Performance Guarantees for Quantum Neural Estimation of Entropies
Sreejith Sreekumar, Ziv Goldfeld, Mark M. Wilde·Nov 24, 2025
Estimating quantum entropies and divergences is an important problem in quantum physics, information theory, and machine learning. Quantum neural estimators (QNEs), which utilize a hybrid classical-quantum architecture, have recently emerged as an ap...
Neural Architecture Search for Quantum Autoencoders
Hibah Agha, Samuel Yen-Chi Chen, Huan-Hsin Tseng +1 more·Nov 24, 2025
In recent years, machine learning and deep learning have driven advances in domains such as image classification, speech recognition, and anomaly detection by leveraging multi-layer neural networks to model complex data. Simultaneously, quantum compu...
Flexible Genetic Algorithm for Quantum Support Vector Machines
Nguyen Minh Duc, Vu Tuan Hai, Le Bin Ho +1 more·Nov 24, 2025
Quantum Support Vector Machines (QSVM) is one of the most promising frameworks in quantum machine learning, yet their performance depends on the design of the feature map. Conventional approaches rely on fixed quantum circuits, which often fail to ge...
Diagram-to-Circuit QNLP for Financial Sentiment Analysis
T. Sakuma·Nov 24, 2025
We study a \emph{QDisCoCirc}-inspired, chunked diagram-to-circuit quantum natural language processing (QNLP) model for three-class sentiment classification of financial texts. In our classical simulations, we keep the Hilbert-space dimension manageab...
