Exponential Analysis for Entanglement Distillation
Zhiwen Lin, Ke Li, Kun Fang·Jan 15, 2026
Historically, the focus in entanglement distillation has predominantly been on the distillable entanglement, and the framework assumes complete knowledge of the initial state. In this paper, we study the reliability function of entanglement distillat...
Lambert W Function Framework for Graphene Nanoribbon Quantum Sensing: Theory, Verification, and Multi-Modal Applications
F. A. Chishtie, K. Roberts, N. Jisrawi +3 more·Jan 15, 2026
We establish a rigorous mathematical framework connecting graphene nanoribbon quantum sensing to the Lambert W function through the finite square well (FSW) analogy. The Lambert W function, defined as the inverse of $f(W) = We^W$, provides exact anal...
Computing Statistical Properties of Velocity Fields on Current Quantum Hardware
Miriam Goldack, Yosi Atia, Ori Alberton +1 more·Jan 15, 2026
Quantum algorithms are gaining attention in Computational Fluid Dynamics (CFD) for their favorable scaling, as encoding physical fields into quantum probability amplitudes enables representation of two to the power of n spatial points with only n qub...
Fluctuation-induced quenching of chaos in quantum optics
Mei-Qi Gao, Song-hai Li, Xun Li +3 more·Jan 15, 2026
Recent studies have extensively explored chaotic dynamics in quantum optical systems through the mean-field approximation, which corresponds to an ideal, fluctuation-free scenario. However, the inherent sensitivity of chaos to initial conditions impl...
Bridging Superconducting and Neutral-Atom Platforms for Efficient Fault-Tolerant Quantum Architectures
Xiang Fang, Jixuan Ruan, Sharanya Prabhu +4 more·Jan 15, 2026
The transition to the fault-tolerant era exposes the limitations of homogeneous quantum systems, where no single qubit modality simultaneously offers optimal operation speed, connectivity, and scalability. In this work, we propose a strategic approac...
Casimir interactions as a probe of broadband optical response
Calum F. Shelden, Jeremy N. Munday·Jan 15, 2026
Casimir forces arise from quantum electromagnetic fluctuations and depend on the dielectric response of interacting materials across the entire frequency spectrum. Although this dependence is central to Lifshitz theory of the Casimir effect, the form...
Classical simulation of a quantum circuit with noisy magic inputs
Jiwon Heo, Sojeong Park, Changhun Oh·Jan 15, 2026
Magic states are essential for universal quantum computation and are widely viewed as a key source of quantum advantage, yet in realistic devices they are inevitably noisy. In this work, we characterize how noise on injected magic resources changes t...
Pseudomode approach to Fano effect in dissipative cavity quantum electrodynamics
Kazuki Kobayashi, Tatsuro Yuge·Jan 15, 2026
We study the Fano effect in dissipative cavity quantum electrodynamics, which originates from the interference between the emitter's direct radiation and that mediated by a cavity mode. Starting from a two-level system coupled to a structured reservo...
Starfield: Demand-Aware Satellite Topology Design for Low-Earth Orbit Mega Constellations
Shayan Hamidi Dehshali, Tzu-Hsuan Liao, Shaileshh Bojja Venkatakrishnan·Jan 15, 2026
Low-Earth orbit (LEO) mega-constellations are emerging as high-capacity backbones for next-generation Internet. Deployment of laser terminals enables high-bandwidth, low-latency inter-satellite links (ISLs); however, their limited number, slow acquis...
Geometric Criteria for Complete Mode Conversion in Detuned Systems via Piecewise-Coherent Modulation
Awanish Pandey·Jan 15, 2026
Static phase detuning fundamentally constrains coherent state transfer in asymmetric classical and quantum systems. We introduce a Bloch-sphere formulation for piecewise-coherent modulation that recasts coupled-mode dynamics as geometric trajectories...
Minimally Truncated SU(3) Lattice Gauge Theory and String Tension
Vincent Chen, Berndt Müller, Xiaojun Yao·Jan 15, 2026
We study SU(3) gauge theory on small lattices in the minimal (qutrit) electric field truncation retaining only the ${\bf 1}, {\bf 3}, {\bf \overline{3}}$ representations for the link variables. Explicit expressions are given for the Kogut-Susskind Ha...
Optimal qudit overlapping tomography and optimal measurement order
Shuowei Ma, Qianfan Wang, Lvzhou Li +1 more·Jan 15, 2026
Quantum state tomography is essential for characterizing quantum systems, but it becomes infeasible for large systems due to exponential resource scaling. Overlapping tomography addresses this challenge by reconstructing all $k$-body marginals using ...
Anomalous transport in quasiperiodic lattices: emergent exceptional points at band edges and log-periodic oscillations
Jinyuan Shang, Haiping Hu·Jan 15, 2026
Quasiperiodic systems host exotic transport regimes that are distinct from those found in periodic or disordered lattices. In this work, we study quantum transport in the Aubry-André-Harper lattice in a two-terminal setup coupled to zero-temperature ...
Towards Minimal Fault-tolerant Error-Correction Sequence with Quantum Hamming Codes
Sha Shi, Xiao-Yang Xu, Min-Quan Cheng +2 more·Jan 15, 2026
The high overhead of fault-tolerant measurement sequences (FTMSs) poses a major challenge for implementing quantum stabilizer codes. Here, we address this problem by constructing efficient FTMSs for the class of quantum Hamming codes $[\![2^r-1, 2^r-...
Contextuality Derived from Minimal Decision Dynamics: Quantum Tug-of-War Decision Making
Song-Ju Kim·Jan 15, 2026
Decision making often exhibits context dependence that challenges classical probability theory. While quantum cognition has successfully modeled such phenomena, it remains unclear whether quantum probability is merely a convenient assumption or a nec...
Hybrid superinductance with Al/InAs
Junseok Oh, Ido Levy, Tyler Cowan +4 more·Jan 15, 2026
We report microwave spectroscopy of Josephson junctions chains made from an epitaxial Al/InAs heterostructure. The chains exhibit superinductance, with characteristic wave impedance exceeding $R_{Q} = \hbar/(2e)^{2}$. The planar nature of the junctio...

Fatemeh Ghasemi, Yousung Kang, Yukio Kawashima +1 more·Jan 15, 2026
Accurately capturing electron correlation in large-scale molecular systems remains one of the foremost challenges in quantum chemistry and a primary driver for the development of quantum algorithms. Classical configuration-interaction methods, while ...
Reentrant topological phases and entanglement scalings in moiré-modulated extended Su-Schrieffer-Heeger Model
Guo-Qing Zhang, L. F. Quezada, Shi-Hai Dong·Jan 15, 2026
Recent studies of moiré physics have unveiled a wealth of opportunities for significantly advancing the field of quantum phase transitions. However, properties of reentrant phase transitions driven by moiré strength are poorly understood. Here, we in...
Double Markovity for quantum systems
Masahito Hayashi, Jinpei Zhao·Jan 15, 2026
The subadditivity-doubling-rotation (SDR) technique is a powerful route to Gaussian optimality in classical information theory and relies on strict subadditivity and its equality-case analysis, where double Markovity is a standard tool. We establish ...
Holographic entropy inequalities pass the majorization test
Bartlomiej Czech, Yichen Feng, Xianlai Wu +1 more·Jan 15, 2026
Quantities computed by minimal cuts, such as entanglement entropies achievable by the Ryu-Takayanagi proposal in the AdS/CFT correspondence, are constrained by linear inequalities. We prove a previously conjectured property of all such constraints: A...
