Hybrid Quantum-Classical Dispatching for High-Renewable Power Systems:A Noise-Resilient Variational Approach with Real-World Validation
Fu Zhang, Yuming Zhao·Nov 17, 2025
This study introduces a hybrid quantum-classical dispatching framework designed for power systems with high renewable penetration. The proposed method integrates a variational quantum algorithm with classical optimization to provide noise-resilient p...
Optimal Multiparameter Quantum Estimation of Magnonic Couplings in a Magnomechanical Cavity
Adnan Naimy, Abdallah Slaoui, Abderrahim Lakhfif +1 more·Nov 15, 2025
In this work, we introduce an experimentally viable scheme to enhance the simultaneous estimation precision of the couplings $G_{mc}$ and $G_{mb}$, with a particular focus on the performance of heterodyne detection. By comparing simultaneous and indi...
QMA Complete Quantum-Enhanced Kyber: Provable Security Through CHSH Nonlocality
Ilias Cherkaoui, Indrakshi Dey·Nov 15, 2025
Post-quantum cryptography (PQC) must secure large-scale communication systems against quantum adversaries where classical hardness alone is insufficient and purely quantum schemes remain impractical. Lattice-based key encapsulation mechanisms (KEMs) ...
Photonic spin Hall effect in $\mathcal{PT}$-symmetric non-Hermitian cavity magnomechanics
Shah Fahad, Muzamil Shah, Gao Xianlong·Nov 15, 2025
Non-Hermitian cavity magnomechanics (CMM), which incorporates the magnon-photon and magnon-phonon interactions simultaneously, enables rich physical phenomena, including exceptional-point-enhanced sensing, and offers pathways toward topological trans...
Hybrid Predictive Quantum Feedback: Extending Qubit Lifetimes Beyond the Wiseman-Milburn Limit
Ali Abu-Nada, Aryan Iliat, Russell Ceballos·Nov 15, 2025
Amplitude damping fundamentally limits qubit lifetimes by irreversibly leaking energy and information into the environment. Standard Wiseman--Milburn feedback offers only modest improvement because it acts on a single measured quadrature and its corr...
Leveraging Quantum-Based Architectures for Robust Diagnostics
Shabnam Sodagari, Tommy Long·Nov 15, 2025
The objective of this study is to diagnose and differentiate kidney stones, cysts, and tumors using Computed Tomography (CT) images of the kidney. This study leverages a hybrid quantum-classical framework in this regard. We combine a pretrained ResNe...
Compact cavity-dressed Hamiltonian framework at arbitrarily strong light-matter coupling
Jakub Garwoła, Dvira Segal·Nov 14, 2025
We present a non-perturbative Hamiltonian mapping method for quantum systems strongly coupled to a quantized field mode (cavity), yielding compact closed-form representations of hybrid light-matter systems. The mapping method builds on an entangling ...
Solving a Nonlinear Eigenvalue Equation in Quantum Information Theory: A Hybrid Approach to Entanglement Quantification
Abrar Ahmed Naqash, Fardeen Ahmad Sofi, Mohammad Haris Khan +1 more·Nov 14, 2025
Nonlinear eigenvalue equations arise naturally in quantum information theory, particularly in the variational quantification of entanglement. In this work, we present a hybrid analytical and numerical framework for evaluating the geometric measure of...
A New Quantum Secure Time Transfer System
Ravi Singh Adhikari, Aman Gupta, Anju Rani +2 more·Nov 13, 2025
High-precision clock synchronization is essential for a wide range of network-distributed applications. In the quantum space, these applications include communication, sensing, and positioning. However, current synchronization techniques are vulnerab...
Efficient quantum Gibbs sampling of stabilizer codes using hybrid computation
Ivan H. C. Shum, Angela Capel·Nov 13, 2025
We present hybrid Gibbs sampling algorithms for the stabilizer code Hamiltonians of the rotated surface code and the toric code with only local quantum algorithms, using $\sim L/2$ quantum circuit depth to prepare the Gibbs state of the rotated surfa...
Diffusion in the stochastic Klein-Gordon equation
Jonathan Oppenheim, Emanuele Panella·Nov 13, 2025
Theories of gravity in which the metric is fundamentally classical predict stochastic fluctuations in the gravitational field. In this article, we study the stochastic Klein-Gordon equation as a starting point to understand the phenomenology of linea...

We present a hybrid variational framework for quantum optimal control aimed at high-fidelity state transfer in spin chains. The system dynamics are discretized and compiled into a parameterized circuit, where deterministic two-qubit blocks implement ...
Green Function Invariants for Floquet Topological Superconductivity Induced by Proximity Effects
Mohamed Assili, Panagiotis Kotetes·Nov 12, 2025
We bring forward a Green function approach for the prediction of Floquet topological phases in driven superconductor-semiconductor hybrids. Although it is common to treat the superconducting component as a mere Cooper-pair reservoir, it was recently ...
Superdiffusive transport protected by topology and symmetry in all dimensions
Shaofeng Huang, Yu-Peng Wang, Jie Ren +1 more·Nov 12, 2025
Superdiffusion is an anomalous transport behavior. Recently, a new mechanism, termed the ``nodal mechanism," has been proposed to induce superdiffusion in quantum models. However, existing realizations of the nodal mechanism have so far been proposed...
