A graphical framework for proving holographic entanglement entropy inequalities in multipartite systems
Chia-Jui Chou, Hans B. Lao, Yi Yang·Dec 21, 2025
We present a graphical method for proving holographic entanglement entropy inequalities (HEIs) in general multipartite systems. By introducing a geometric representation of the entanglement structure, we develop a systematic approach that enables one...
Density of scattering resonances in a disordered system
M. S. Kurilov, P. M. Ostrovsky·Dec 21, 2025
Reflection of particles from a disordered or chaotic medium is characterized by a scattering matrix that can be represented as a superposition of resonances. Each resonance corresponds to an eigenstate inside the medium and has a width related to the...
On the construction of graph models realizing given entropy vectors
Veronika E. Hubeny, Massimiliano Rota·Dec 21, 2025
We present an efficient algorithm for the construction of a holographic simple tree graph model that realizes a given entropy vector, subject to a specific ``chordality'' condition first introduced in arXiv:2412.18018. We further develop the toolkit ...
Identification and Optimization of Accurate Spin Models for Open-Shell Carbon Ladders with Matrix Product States
Andoni Agirre, Thomas Frederiksen, Geza Giedke +1 more·Dec 21, 2025
Open-shell nanographenes offer a controlled setting to study correlated magnetism emerging from $π$-electron systems. We analyze oligo(indenoindene) molecules, non-bipartite carbon ladders whose tight-binding spectra feature a gapped, weakly dispersi...
Temperature-enhanced quantum sensing for the cutoff frequency of Ohmic environments
Yuan Ji-Bing, Song Ya-Ju, Tang Shi-Qing +2 more·Dec 21, 2025
We investigate the quantum sensing performance of a dephasing qubit as a probe in Ohmic environments, characterized by the coupling strength $η$, the Ohmicity parameter $s$, and the cutoff frequency $ω_c$ to be estimated. The performance is quantifie...
Toward Live Noise Fingerprinting in Quantum Software Engineering
Avner Bensoussan, Elena Chachkarova, Karine Even-Mendoza +3 more·Dec 21, 2025
Contemporary quantum computers are inherently noisy, posing significant challenges for the development and testing of quantum software. Simplified or outdated noise assumptions can lead to incorrect assessments of program correctness, obscure debuggi...
Kicked fluxonium with quantum strange attractor
Alexei D. Chepelianskii, Dima L. Shepelyansky·Dec 21, 2025
The quantum dissipative time evolution of a fluxonium under a pulsed field (kicks) is studied numerically and analytically. In the classical limit the system dynamics is converged to a strange chaotic attractor. The quantum properties of this system ...
A Hidden Quantum Markov model framework for Entanglement and Topological Order in the AKLT Chain
Abdessatar Souissi, Amenallah Andolsi·Dec 21, 2025
This paper introduces a hidden quantum Markov models (HQMMs) framework to the Affleck-Kennedy-Lieb-Tasaki (AKLT) state-a cornerstone example of a symmetry-protected topological (SPT) phase. The model's observation system is the physical spin-1 chain,...
Post-Newtonian Constraints on Semiclassical Gravity with Quantum Superpositions
Hollis Williams·Dec 21, 2025
Semiclassical gravity, in which a classical spacetime is sourced by the quantum expectation value of the stress-energy tensor, is a standard framework for describing the gravitational interaction of quantum matter. In the nonrelativistic limit this a...
Image Denoising via Quantum Reservoir Computing
Soumyadip Das, Luke Antoncich, Jingbo B. Wang·Dec 21, 2025
Quantum Reservoir Computing (QRC) leverages the natural dynamics of quantum systems for information processing, without requiring a fault-tolerant quantum computer. In this work, we apply QRC within a hybrid quantum classical framework for image deno...
Bell Nonlocality as a Covariance Obstruction in Locally Covariant Quantum Field Theory
Joseph Samper Finberg·Dec 21, 2025
Locally covariant algebraic quantum field theory (LCQFT) satisfies Einstein causality through microcausality and operational no-signalling, yet Bell-type correlations persist in entangled field states across spacelike regions. We demonstrate that thi...
A regularisation method to obtain analytical solutions to the de Broglie Bohm wave equation
Anand Aruna Kumar, S. K. Srivatsa, Rajesh Tengli·Dec 21, 2025
We develop a variational regularisation framework that enables analytical solutions of the stationary de~Broglie--Bohm wave equation. The formulation begins with a Fisher-information-augmented action functional for the probability density and phase f...
Global approximations to correlation functions of strongly interacting quantum field theories
Yuanran Zhu, Yang Yu, Efekan Kökcü +2 more·Dec 20, 2025
We introduce a method for constructing global approximations to correlation functions of strongly interacting quantum field theories, starting from perturbative results. The key idea is to employ interpolation method, such as the two-point Padé expan...
Read-Only Opacity and Restricted-Access Inference on Quantum Memories via U-QRAM
Leonardo Bohac·Dec 20, 2025
Universal QRAM (U-QRAM) is a fixed, data-independent unitary interface that implements coherent random-access reads relative to a designated computational "truth-table" basis on the memory register. This work studies restricted-access inference: the ...
Two Photon Tripartite Entanglement Transfer via Time-Multiplexed Quantum Walks
Jonas Lammers, Federico Pegoraro, Philip Held +3 more·Dec 20, 2025
Photonic multidimensional quantum networks (MDQN), where individual subsystems are encoded using multiple degrees of freedom and photons, are an emerging platform for quantum algorithms because they offer high scalability. The distribution of non-cla...
Quantum Nonlocality and Device-Independent Randomness Robust to Relaxations of Bell Assumptions
Ravishankar Ramanathan, Yuan Liu·Dec 20, 2025
The question of certifying quantum nonlocality under a relaxation of the assumptions in the Bell theorem has gained traction, with potential for device-independent applications under weak seeds and cross-talk. Recently, it was shown that quantum nonl...
Cyber Threat Detection Enabled by Quantum Computing
Zisheng Chen, Zirui Zhu, Xiangyang Li·Dec 20, 2025
Threat detection models in cybersecurity must keep up with shifting traffic, strict feature budgets, and noisy hardware, yet even strong classical systems still miss rare or borderline attacks when the data distribution drifts. Small, near-term quant...

Mohammadreza Saghafi, Lamine Mili, Karlton Wirsing·Dec 20, 2025
We present a multifractal analysis of time series data obtained by repeatedly running a single-qubit quantum circuit on IBM superconducting quantum computers, in which the measurement outcomes are recorded as the number of zeros. By applying advanced...
