SMILES-Inspired Transfer Learning for Quantum Operators in Generative Quantum Eigensolver
Zhi Yin, Xiaoran Li, Shengyue Zhang +2 more·Sep 24, 2025
Given the inherent limitations of traditional Variational Quantum Eigensolver(VQE) algorithms, the integration of deep generative models into hybrid quantum-classical frameworks, specifically the Generative Quantum Eigensolver(GQE), represents a prom...
Exploiting Non-Markovian Memory Effects for Robust Quantum Teleportation
Safae Gaidi, Nour-Eddine Abouelkhir, Abdallah Slaoui +2 more·Sep 23, 2025
The reliable transmission of quantum information remains a central challenge in the presence of environmental noise. In particular, maintaining high teleportation fidelity in open quantum systems is hindered by decoherence, which disrupts quantum coh...
Quantum Annealing for Minimum Bisection Problem: A Machine Learning-based Approach for Penalty Parameter Tuning
Renáta Rusnáková, Martin Chovanec, Juraj Gazda·Sep 23, 2025
The Minimum Bisection Problem is a well-known NP-hard problem in combinatorial optimization, with practical applications in areas such as parallel computing, network design, and machine learning. In this paper, we examine the potential of using D-Wav...
Intrinsic-perturbation induced anomalous higher-order boundary states in non-Hermitian systems
Hui-Qiang Liang, Zuxuan Ou, Linhu Li +1 more·Sep 23, 2025
The behavior of higher-order boundary states in non-Hermitian systems is elusive and thereby finding the mechanism behind these states is both essential and significant. Here, we uncover a novel mechanism that induces anomalous higher-order boundary ...
Trading modes against energy
Lukas Brenner, Beatriz Dias, Robert Koenig·Sep 23, 2025
We ask how much energy is required to weakly simulate an $n$-qubit quantum circuit (i.e., produce samples from its output distribution) by a unitary circuit in a hybrid qubit-oscillator model. The latter consists of a certain number of bosonic modes ...
Octahedral dynamics and local symmetry in hybrid perovskite FAPbI3 under thermal excitation
H. Joshi, K. C. Bhamu, A. Shankar +2 more·Sep 23, 2025
Density Functional Theory (DFT) and ab initio molecular dynamics (AIMD) simulations have been employed to investigate the evolution of local motifs within the tetragonal phase of FAPbI3 under thermal excitation. Our results reveal a distinct broadeni...
Localization and topological signatures under periodic twisting
James Walkling, Antonio Štrkalj, F. Nur Ünal·Sep 22, 2025
We theoretically explore a dynamical generalization of the Aubry-André model in two dimensions formed by superimposing two square-lattice potentials. Motivated by the rich physics emerging at different twist angles between the two lattices at equilib...
Hybrid Trapping of Cold Atoms with Surface Forces and Blue-Detuned Evanescent Light on a Nanophotonic Waveguide
Riccardo Pennetta, Antoine Glicenstein, Philipp Schneeweiss +2 more·Sep 22, 2025
We demonstrate a novel hybrid nanophotonic trap for cold neutral atoms, leveraging surface forces for attraction and blue-detuned evanescent light for repulsion. We attribute the attractive potential to a combination of Casimir-Polder interactions an...
Digital controllability of transverse field Ising chains
Vincenzo Roberto Arezzo, Ruiyi Wang, Kiran Thengil +2 more·Sep 22, 2025
Quantum Annealing (QA) encounters limitations when the energy gap along the annealing path becomes exponentially small, leading to impractically long runtimes. In contrast, the success of hybrid digital methods like the Quantum Approximate Optimizati...

Chi-Sheng Chen, Aidan Hung-Wen Tsai·Sep 21, 2025
We formulate automated market maker (AMM) \emph{rebalancing} as a binary detection problem and study a hybrid quantum--classical self-attention block, \textbf{Quantum Adaptive Self-Attention (QASA)}. QASA constructs quantum queries/keys/values via va...

The emerging field of Quantum Machine Learning (QML) has shown promising advantages in accelerating processing speed and effectively handling the high dimensionality associated with complex datasets. Quantum Computing (QC) enables more efficient data...
Formation of Cavity-Polaritons via High-Order Van Hove Singularities
Igor Gianardi, Michele Pini, Francesco Piazza·Sep 19, 2025
We consider polaritons formed by hybridizing particle-hole excitations of an insulating phase with a cavity photon at sub-gap frequencies, where absorption is suppressed. The strength of the hybridization is driven by the Van Hove singularity in the ...
