ARGON: A GNN-Empowered Compilation Framework for Scalable Neutral Atom Computing

Wenjie Sun, Xiaoyu Li, Zhigang Wang +3 more·Jul 23, 2026

Neutral atom quantum systems offer a promising pathway to large-scale quantum computing due to high qubit uniformity and flexible connectivity. To exploit this architecture, compilers must coordinate dynamic atom transport alongside highly parallel e...

Quantum Circuit Fragments and Link Products in Continuous Variables

Amalina Lai, Graeme D. Berk, Minjeong Song +1 more·Jul 23, 2026

Quantum circuits are often drawn as complete processes, with fixed inputs and outputs. In many quantum-information tasks, however, the natural object is only a fragment of such a circuit: an unknown source of non-Markovian noise to be probed, a subro...

Do emulated quantum circuits change what CNNs look at? Performance and explainability comparison in medical image classification

Guillermo Rubiños Rodríguez, Martín Ottavianelli, Mateo Alonso +4 more·Jul 23, 2026

Numerous studies have analyzed the use of hybrid quantum-classical convolutional neural networks as a promising alternative to classical deep learning. However, network components on quantum hardware impose fundamental limitations, while the scalabil...

Basis-independent coherence and quantum correlations in two dipole-dipole-coupled electrons in double quantum-dot molecules

Zakaria Bouafia, Neha Pathania, Mostafa Mansour·Jul 23, 2026

This work examines the thermal dynamics of basis-independent quantum coherence and correlation-based quantum resources for two dipole-dipole-coupled electrons confined in spatially separated quantum-dot (QD) molecules. Single-dot quantum superpositio...

Characterising extremal decoherence by quantum measurement incompatibility

Daniel McNulty, William Townsend, Jukka Kiukas·Jul 23, 2026

Decoherence, when viewed in the Heisenberg picture, can turn incompatible measurements into jointly measurable ones. This provides an observable-level description of emergent classicality in terms of the incompatibility destroyed by a noise channel. ...

Duality constrains optimal thresholds in quantum error correction

Lucas H. English, Haoyuan Luo, Yangming Wang +3 more·Jul 23, 2026

Error correction thresholds are often treated as the primary figure of merit for comparing quantum error-correcting code families. We show that the optimal error correction threshold for many commonly considered codes is constrained to a single unive...

Exceptional-Point Geometry of Weak Topological Boundary States

Rafael A. Molina, Kevin González, Pedro A. Orellana·Jul 23, 2026

In this article, we demonstrate that weak topology can be formulated geometrically in terms of exceptional singularities of an analytically continued Bloch Hamiltonian. A general plaquette chiral model in two dimensions serves as a minimal realizatio...

Approximate Quantum State Preparation Through Proximal Policy Optimization

Marco Mordacci, Michele Amoretti·Jul 23, 2026

In this work, a quantum architecture search framework for approximate quantum state preparation (QSP) is proposed. QSP is a challenging task, since the search space grows exponentially with the number of qubits, making the identification of the optim...

Entanglement, Evolutionary Stability, and Strategy-Space Dependence in an EWL Quantum Game

Azhar Iqbal, Derek Abbott·Jul 23, 2026

We examine how Eisert--Wilkens--Lewenstein (EWL) quantization affects evolutionary stability in a symmetric $2\times2$ game whose interior mixed Nash equilibrium is not evolutionarily stable. In the restricted two-parameter EWL strategy space, the qu...

Conditional probabilities in quantum-optical settings

Alfredo Luis·Jul 23, 2026

We examine conditional probabilities derived from the joint noisy measurement of two complementary observables. We show that conditioning on one variable can lead to reduction of uncertainty in the other one, even completely eliminating uncertainty. ...

Picosecond-resolved entanglement distribution over an urban free-space channel

Alessandro Laneve, Fabrizio Cienzo, Santiago Gomez +18 more·Jul 23, 2026

Time-evolving entangled states describe quantum particles whose correlations evolve in time according to a well-defined dynamics. Such states can be generated in a variety of physical systems and are promising resources for several quantum technologi...

Vacuum-induced interference in light scattering by multilevel atomic chains

Aleksei Konovalov, Giovanna Morigi, Nicola Piovella·Jul 23, 2026

We investigate cooperative light scattering by an ordered chain of multilevel atoms, which possess two quasi-resonant transitions with parallel dipole moments. Interference between dipole transitions induced by coupling with the vacuum gives rise to ...

Fermionic pairs, from the surface to the bulk

Sandra Brandstetter, Carl Heintze, Fabian Brauneis +4 more·Jul 22, 2026

Fermion pairing underlies collective quantum phenomena across widely different forms of matter. In extended systems such as ultracold Fermi gases, pairing is commonly understood through the BCS--BEC crossover, where the pair size evolves from large, ...

Efficiently Simulable Pauli Correlation Encoding

Daniele Lizzio Bosco, Gabriel Matos, Chen-Yu Liu +4 more·Jul 22, 2026

Pauli Correlation Encoding (PCE) is a heuristic framework for binary optimisation that encodes classical variables into many-body Pauli observables. While PCE requires fewer qubits than other approaches, it relies on estimating a large number of Paul...

Qoreo: Choreographic Programming for Quantum Distributed Systems

Jennifer Paykin, Steven Baldasty, Joseph P. Near +1 more·Jul 22, 2026

Programming distributed quantum systems requires multiple actors to coordinate precise sequences of quantum operations, classical communication, and entanglement generation. Writing such protocols directly as distributed processes is tedious and erro...

Arnold--Nielsen Geometry for Complexity-Deformed Noncommutative Transport

Alberto Acevedo, Antonio Falcó·Jul 22, 2026

We deform the Carlen--Maas--Wirth framework for noncommutative dynamical optimal transport by an Arnold--Nielsen type complexity operator. A positive state-independent operator $G$ compatible with the Hilbert bimodule structure of a noncommutative di...

FMRP-LEAN: A HIPAA-Compliant AI-Augmented LIMS Architecture for End-to-End Clinical Assay Workflow Optimization

Eva McCord, Ernest Pedapati, Zag ElSayed·Jul 22, 2026

Clinical biomarker workflows in translational research settings often rely on spreadsheet-driven tracking, manual quality control (QC) reconciliation, and loosely integrated systems, resulting in limited state visibility, delayed reporting, and incre...

Statevector-Referenced Geometry Survival of a Four-Qubit ZZ Quantum Kernel on IBM Quantum Hardware: A Fixed-Subset Diagnostic Across Three Execution Configurations

Rostyslav Sipakov·Jul 22, 2026

Quantum-kernel methods encode a dataset's geometry in a Gram matrix, so learning claims on hardware kernels assume the intended geometry survives execution. We measure that survival for one frozen four-qubit ZZ feature-map kernel on $N=24$ real indoo...

PolySim: Deterministic Polynomial Surrogates for Cross-Modal Retrieval on CiM

Xinzhao Li, Charles Power, Pengyu Ren +10 more·Jul 22, 2026

Cross-modal retrieval on edge devices benefits from probabilistic embeddings that capture semantic uncertainty, but deploying them on compute-in-memory (CiM) hardware remains an open problem. The core difficulty is a sampling gap: probabilistic metho...
