AI, Trust, and Teaming: The Humans-as-Handlers Approach for Autonomous and Opaque AI Systems
Nathan G. Wood·Jul 1, 2026
Artificial intelligence (AI) is becoming ubiquitous, and across domains, increasingly autonomous systems are carrying out tasks which raise significant ethical and legal challenges which demonstrate a need for strong human-machine teams rooted in tru...
Surface charges in a Rydberg atom-nanowaveguide hybrid quantum system
Aswathy Raj, Anna Kortel, Krishna Jadeja +4 more·Jul 1, 2026
Hybrid quantum platforms based on highly excited Rydberg atoms coupled to nanophotonics devices offer a promising route toward scalable quantum networks and integrated quantum technologies. However, the close proximity of Rydberg atoms to dielectric ...
Quantum Memory Advantage from Contextuality
Shiroman Prakash·Jul 1, 2026
Quantum contextuality is a vital non-classical resource, yet illuminating the precise mechanisms through which it enables unconditional computational advantages remains a challenge. We translate graph-theoretic formulations of contextuality into an u...
A Versatile Analytical Model for Fast and Accurate Determination of Feedline-Coupled Resonators for Superconducting Qubit Readout
Zhen Luo, Lea Richard, Ivan Tsitsilin +4 more·Jul 1, 2026
Superconducting quantum chips commonly utilize quarter-wavelength (λ/4) transmission line resonators as readout circuits. An analytical model for the accurate determination of resonance frequencies and coupling Q-factors of feedline-coupled supercond...
Scalable Security and Migration-Aware SFC Provisioning in LEO Satellite Networks
Mohammed Mahyoub, Wael Jaafar, Sami Muhaidat +1 more·Jul 1, 2026
Low Earth orbit (LEO) satellite constellations are emerging as a backbone for global 6G connectivity, where independent tenant slices share orbital infrastructure, each requiring an ordered chain of security virtual network functions (VNFs). Because ...
Dependency-Aware Circuit Scheduling for Multi-Core Quantum Systems to Minimize Makespan
Rajeswari Suance P S, Ruchika Gupta, Maurizio Palesi +1 more·Jul 1, 2026
Multi-core quantum computing architectures have emerged as a promising solution to the qubit scalability limitations of monolithic NISQ devices. Quantum algorithms are expressed as quantum circuits composed of single- and two-qubit gates. However, ci...
Bridging quantum mechanics and nonlinear optics in Raman scattering
Naoki Fukutake, Hideaki Kano·Jul 1, 2026
We present a theoretical framework for spontaneous Raman scattering that fundamentally bridges quantum-mechanical and nonlinear-optical approaches. By conceptualizing spontaneous Raman scattering as a stimulated Raman gain or loss event seeded by the...
Closed-loop control for two-qubit gates with trapped ions
Eduardo J. Páez, Seyed Shakib Vedaie, Barry C. Sanders·Jul 1, 2026
State-of-the-art two-qubit gates with trapped ions employ open-loop control that rely on simplified models to precompute control sequences. Our aim is to introduce closed-loop control for two-qubit gates to correct disturbances as they occur during t...
NATO and Emerging Technologies: The Alliance's Shifting Approach to Military Innovation
Stephen Herzog, Dominika Kunertova·Jul 1, 2026
In the current era of great-power competition and the diffusion of emerging disruptive technologies on the battlefield, NATO's approach to coordinating the development, adoption, and standardization of new technologies is changing from its practices ...
Holographic Quantum Transformer: A Generalist Neuro-Symbolic Architecture for Solving Frustrated Systems via Generative Attention
Xingran Guo, Tiaojie Xiao, Jie Liu +1 more·Jul 1, 2026
Simulating two-dimensional frustrated quantum matter is a grand challenge due to the sign problem and exponential Hilbert space complexity. In this work, we introduce the Holographic Quantum Transformer (HQT), a physics-inspired generative architectu...
Subsystem Thermalization and Work Statistical Characterizations of Floquet Dynamics
Feng-Li Lin, Ching-Yu Huang·Jul 1, 2026
We study Floquet thermalization in a periodically driven quantum non-integrable Ising chain by combining two operational diagnostics: subsystem thermalization and work statistics. For generic interacting Floquet systems, stroboscopic dynamics lead to...
When AI meets quantum information: A comprehensive review
Min Chen, Yu Gan, Xin Jin +15 more·Jul 1, 2026
Artificial intelligence (AI) and quantum information (QI) are rapidly co-evolving. AI is becoming a practical tool for learning, designing, controlling, and verifying quantum systems, while QI offers new computational models, representational structu...
Extreme volume monogamy via bound-state engineering
Wen-Jie Zhang, Jun-Hong An·Jul 1, 2026
Quantum steering ellipsoid (QSE) provides a faithful representation of a two-qubit state. When extended to tripartite systems, the steerability from a trusted party to different receivers is subject to volume monogamy relations, which only constrain ...
Wallis Products from the Four-Dimensional Singular Harmonic Oscillator
Bin Ye, Ruitao Chen, Lei Yin·Jul 1, 2026
We present a variational derivation of the Wallis product and its reciprocal from the four-dimensional singular harmonic oscillator. The inverse-square interaction is absorbed into an effective angular parameter $ν$, so that the lowest exact energy i...
Leggett-Garg inequality in the massive scalar vacuum: No violation under spacelike-separated measurements
Yang Xiang·Jul 1, 2026
We overcome the long-standing noninvasive measurability (NIM) challenge in Leggett-Garg tests by exploiting the causal structure of quantum field theory (QFT). Our protocol uses three independent ensembles of the vacuum state, each measured by a diff...
Quantum advantage prediction in turbulent free-space quantum illumination
Yu Tang, Beining Xia, Qianqian Liu +3 more·Jul 1, 2026
Quantum illumination offers a significant theoretical advantage for target detection in high background noise environments. However, its practical deployment in free-space channels is hindered by atmospheric turbulence. Stochastic fluctuations in atm...
