Anyons and Inherently Complex F-symbols
Matthew Buican, Peter Huston, Jiannis K. Pachos·Jul 11, 2026
Anyons in $2+1$ dimensions are not only characterized by exotic braiding statistics but also by intricate fusion properties. Two anyons may fuse into multiple topological charge sectors, and associativity of fusing three anyons to produce a fixed cha...
Hamiltonian Conditions for Dark Modes in Multimode Bosonic Systems
Zuxin Wu, Shengshi Pang·Jul 11, 2026
Dark modes arise when destructive interference prevents selected bosonic degrees of freedom from coupling to environmental channels. We formulate a Hamiltonian criterion for identifying such modes in multimode bosonic systems by separating two requir...
Unified Phase-Space Mapping of Quantum Observables in a Multi-Driven Vapor: Resonance Fluorescence as an Electrometry Probe and Correlation Witness
M. S. Ateto, Emad K. Jaradat, S. M. Abo-Dahab·Jul 11, 2026
We present a unified, geometry-resolved framework for analyzing absorption, resonance fluorescence, entanglement negativity, and phase-space quasiprobability in Doppler-broadened four-level atomic vapor. Using a density-matrix formalism with thermal ...
Fast and accurate AI-based pre-decoders for color codes
Jan Olle, Christopher Chamberland, Muyuan Li +1 more·Jul 11, 2026
Color codes are promising alternatives to surface codes for universal fault-tolerant quantum computing due to their simpler lattice-surgery protocols and the transversal implementation of logical Clifford gates. However, their practical deployment ha...
Quantum Circuit Vision: Cost-Aware Evaluation of Visual AI Agents for Quantum Code Generation
Dongping Liu, Aoyu Zhang, Luyao Zhang·Jul 11, 2026
Can AI agents visually comprehend quantum circuit diagrams and generate verified executable code--and at what cost? We present Quantum Circuit Vision, a cost-aware evaluation framework for multimodal AI agents on quantum circuit visual understanding....
Measurement-induced overconcentration in quantum generative models
Runzhe Mo, Bingzhi Zhang, Quntao Zhuang·Jul 11, 2026
Quantum measurement is a key resource for quantum generative learning, providing intrinsic stochasticity for generating diverse quantum samples. However, in measurement-assisted state-ensemble resampling, repeated measurements can also induce overcon...
Kinetic Inductors Enable Reversible Logic
Erik P. DeBenedictis·Jul 10, 2026
Reversible logic has long promised substantial reductions in energy dissipation, yet prior demonstrations have not scaled to commercially relevant systems. This work presents a quantitative framework for evaluating reversible logic through a process ...
A Conceptual Architecture for Educational Digital Twins Supporting AI Literacy Across Educational and Professional Settings
Antonio Bucchiarone, Riccardo Belliato, Judith Michael +1 more·Jul 10, 2026
In the AI Literacy for Multidisciplinary Professional Readiness and Outreach (AIM-PRO) project, we are creating integrated methods to improve the education on AI literacy. One concept on which the project relies is educational digital twins, that is,...
Phase-switchable nonreciprocal entanglement via magnon squeezing in ring-cavity optomagnomechanics
Z. Imara, A. El Allati, A. Belfakir +2 more·Jul 10, 2026
Cavity optomagnomechanics provides a versatile platform to explore macroscopic quantum correlations, particularly nonreciprocal entanglement. In this work, we propose a theoretical scheme to generate switchable bipartite and tripartite entanglement i...
Nonlinear particle detectors across the Rindler firewall
Matheus H. Zambianco, Eduardo Martín-Martínez·Jul 10, 2026
We investigate Unruh-DeWitt detectors coupled to composite observables of a quantum scalar field, including quadratic coupling to the field momentum and coupling to the local energy density. We develop a distributional framework for evaluating the co...
Silicon-Germanium Heterostructures with Enhanced Valley Splitting for Spin Qubits
David W. Kanaar, Efrain Martinez, Peihong Zhang +1 more·Jul 10, 2026
Achieving valley splittings well in excess of the thermal energy of electrons and avoiding valley excitations is essential for the consistent initialization, operation and readout of gate-defined Si spin qubits. In this work, we present a device-leve...
Local Determinacy of Quantum Master Equations and a Mechanical Interpretation of the Multi-Mode Jaynes-Cummings and Central Spin Models
Jaeha Lee, Miku Ishizaki·Jul 10, 2026
We propose a novel formulation of master equations for open systems wherein the evolution of a state is determined solely by its local behaviour at any point of time. Specifically, our formulation allows for a local interpretation of the workings of ...
Optimality of the free quantum evolution: the general case with nodes
Laura M. Morato·Jul 10, 2026
Extending and refining a preceding work, the free evolution of a quantum wave function, with fixed initial and final modulus, is considered in the general case where nodes are allowed. The method is based on considering a suitable simple functional r...
A Quantum Path to Partial Differential Equations
Xiantao Li·Jul 10, 2026
Partial differential equations are a promising application area for fault-tolerant quantum algorithms, but the subject lies between two communities with different languages: numerical analysis and quantum computation. These lecture notes provide a nu...
Complete measurement of tunnel- and valley-coupling parameters in a silicon double quantum dot
Daniel J. King, Minyoung Kim, J. Reily +4 more·Jul 10, 2026
Tunneling is essential in the initialization, measurement, and control of quantum dot qubits. In silicon, such tunneling connects not only the qubit states but also valley minima in the conduction band on opposite sides of the Brillouin zone, with la...
Lean-QIT: Towards a Formal Infrastructure for Quantum Information Theory
Chengkai Zhu, Ziao Tang, Guocheng Zhen +6 more·Jul 10, 2026
Quantum information theory (QIT) characterizes the capabilities and fundamental limits of quantum information processing, underpinning quantum communication, computation, and error correction. Formalizing its coding theorems requires connecting finit...
A complete ultrametric on von Neumann's incomplete tensor products
Andrew Lesniewski·Jul 10, 2026
We revisit von Neumann's theory of infinite tensor products of Hilbert spaces. On the set $Γ$ of equivalence classes of $C_0$-sequences, which labels the incomplete tensor products inside the complete tensor product, we introduce a natural pseudo-ult...
LLM for EDA in Front-End Design: Challenges and Opportunities
Kangwei Xu, Bing Li, Ulf Schlichtmann·Jul 10, 2026
As chip complexity increases and time-to-market pressures grow, front-end design has become a critical bottleneck in chip development. Recently, Large Language Models (LLMs) have shown great potential in Electronic Design Automation (EDA). Beyond spe...
Fluctuation theorems for thermally isolated driven quantum systems: nonadiabaticity, excess work and strong inequalities
J. V. M. Steimetz, M. Campisi, M. V. S. Bonança·Jul 10, 2026
We expand on the ideas developed by C. Jarzynski in Physica A 552, 122077 (2020), where an integral fluctuation theorem was derived with the aim of obtaining thermodynamic inequalities stronger than those implied by the Jarzynski equality. Restrictin...
Quantum Orchestras: a Concrete Semantics for Recursive Hybrid Programs
Alex Rice, Dominik Leichtle, Kim Worrall +1 more·Jul 10, 2026
Many production quantum programming languages represent hybrid quantum computations by extending a classical base language with a quantum effect, where qubits are addressed by reference, and quantum operations are understood to mutate some external q...
