Coexistence of Magnon-Induced Optical Vortex and Gaussian Beam Scattering Assisted by Rotational Umklapp Process
Ryusuke Hisatomi, Kotaro Taga, Hisakazu Matsuki +3 more·Aug 22, 2026
The exploitation of crystal-lattice symmetries to engineer angular momentum transfer between structured light and magnons marks a novel frontier for optomagnonic research. In Brillouin light scattering, when focused light propagates parallel to an ex...
Reinventing the Single-pixel Imaging Paradigm via Quantum-Operator-Based Signal Processing
Bu-Ran Yu, Yi-Zhu Zhang, Kan-Xu Jia +3 more·Aug 22, 2026
A fundamental bottleneck across modern computational imaging and high-dimensional sensing is the conventional decoupled acquisition-reconstruction hierarchy, which subjects high-dimensional spatial sensing to the classical shot-noise limit and intens...
Breakdown of Aharonov-Bohm cage in Rydberg synthetic lattices: the roles of inhomogeneity and long-range exchange
Li Pan, Xinlu Chen, Hong Zhang +1 more·Aug 22, 2026
While the interaction-induced breakdown of Aharonov-Bohm (AB) cage is typically attributed to uniform bound-pair transport, systems with inhomogeneous exchange interactions realized with Rydberg synthetic lattices exhibit more complex dynamics. Emplo...
Markov Constraints Enhance Identifiability in Quantum Shadow Inversion
Zhixing Chen, Lin Chen·Aug 22, 2026
We study quantum shadow inversion under Markovian locality constraints for four-partite systems arranged along the chain $A$--$B$--$C$--$D$. The goal is to reproduce the expectation value of a fixed endpoint observable $O_{AD}$ after an unknown globa...
Architectural scaling tradeoffs in modular 3D bosonic quantum processors
Shaojiang Zhu, Ugur Alyanak, Tanay Roy +7 more·Aug 22, 2026
We propose a modular three-dimensional bosonic quantum processor built from repeatable coupled-cavity modules linked by configurable interconnect networks. Using hardware-motivated graph-theoretic measures, we compare nearest-neighbor, hub-based, and...
Scalable quantum simulation of continuous-time generative models via tensor networks
Nathan X. Kodama, L. Andrew Wray, Sam Cochran +3 more·Aug 22, 2026
Continuous-time flow and diffusion models are widely used across many application domains, from large-scale deployment in computer vision and protein folding to emerging adoption for modeling language, time series, and quantum states. After training,...
Identifiability and Estimation Precision in Quantum Network Tomography with Imperfect Bell-State Measurements
Athira Kalavampara Raghunadhan, Matheus Guedes De Andrade, Don Towsley +3 more·Aug 21, 2026
We study Quantum Network Tomography (QNT) for end-to-end link-error characterization under imperfect Bell-state measurements (BSMs), where multiplicative coupling between link and measurement parameters makes identifiability non-trivial. For an n-nod...
Programmable Doppler real-space pattern formation in cold atoms
Yijun Tang·Aug 21, 2026
Red-detuned Doppler cooling decelerates atomic motion toward zero velocity, whereas blue-detuned light produces acceleration that separates a cold cloud into finite-velocity packets. Here we combine these complementary dynamics in a programmable spli...
Simultaneous Intensity and Frequency Control for Optical Waveform Generation using an Acousto Optic Modulator
Hariprasad Madathil, Shengzhi Wang, F. Elohim Becerra·Aug 21, 2026
We describe a method for calibrating the response of an acousto-optic modulator (AOM) to enable precise, arbitrary control of the intensity and frequency of optical fields. The method involves characterizing the nonlinear response of the AOM to its i...
Scalable Quantum Key Distribution via GHZ Entanglement and Qubit Reuse
Tasdiqul Islam, Rasman Mubtasim Swargo, Engin Arslan +1 more·Aug 21, 2026
Conventional Quantum Key Distribution (QKD) requires the transmission of qubits proportional to or exceeding the length of the key, as protocols such as BB84 transmit more qubits than the final key size due to basis sifting and privacy amplification....
Measurement and reload costs in direct quantum simulation of nonlinear waves
Ziqing Guo, Viraj Dsouza, Alex Khan +3 more·Aug 21, 2026
Quantum processors encode an N-point field in log_2(N) qubits, which renders nonlinear wave equations an important application for quantum simulation. Nonlinear evolution, however, requires the field values themselves, and these are not directly acce...
Increased cyclicity of atomic transitions via coherent interference of decay paths
Eliza Cornell, Benjamin Pingault, Gergő Thiering +3 more·Aug 21, 2026
Optical readout is a fundamental tool in atomic state measurement, yet the fidelity of optical readout is frequently limited by imperfect photon collection. This can be mitigated when readout occurs on a cycling transition which continuously fluoresc...
Prior-Informed Adaptive Shifts for Sequential Minimal Optimization in Variational Quantum Eigensolvers
Frederik Stalschus, Samuele Pedrielli, Stefan Kühn +3 more·Aug 21, 2026
Sequential minimal optimization methods, such as the Rotosolve and the Nakanishi-Fujii-Todo algorithm (NFT), are widely used for Variational Quantum Eigensolvers (VQEs). These methods optimize one parameter direction at a time, requiring measurements...
Scaling vs entanglement in measurement-induced phase transition for non-integrable systems
Paranjoy Chaki, Protyush Nandi, Subinay Dasgupta +1 more·Aug 21, 2026
We find that the measurement-induced phase transition generated by deterministic global measurements, previously observed in the integrable transverse-field Ising model (TFIM), persists in non-integrable variants of the same. To address this question...
Emulating non-Markovian system-bath dynamics with parametrically driven cavities
Valentin Boettcher, Félix Pellerin, Philippe St-Jean +1 more·Aug 21, 2026
We introduce and characterize a scheme for emulating non-Markovian quantum system-bath dynamics using the discrete electromagnetic field modes of a parametrically driven cavity. In this scheme, the character of a bosonic bath (the form of the bath sp...
Asymptotic entanglement in circle stabilizer states and states forbidding arbitrary vertex-minors
Kenneth Goodenough, Marcelo Sales·Aug 21, 2026
Stabilizer states play a central role in quantum information theory, and understanding their entanglement has motivated a large body of work. A well-studied question in particular is when a stabilizer state $|ψ\rangle$ can be transformed into another...
Many-body ergodicity breaking from wavefunction snapshots
Riccardo Andreoni, Devendra Singh Bhakuni, Marcello Dalmonte +2 more·Aug 21, 2026
Modern quantum experiments can probe many-body wavefunctions through projective measurements, providing snapshots of individual many-body configurations. A fundamental question is whether the intrinsic structure of their measurement distributions can...
Robust cavity metrology beyond the limits of Pound-Drever-Hall
Ibukunoluwa Adisa, Won Chan Lee, Yanqin Huang +3 more·Aug 21, 2026
Precise measurement of the resonance frequencies of microwave and optical cavities is a foundational capability across quantum technologies. One of the highest-performance methods currently available is Pound-Drever-Hall (PDH) spectroscopy, which rel...
Anomalous Local Heat Capacity and Bipartite Entanglement
Jake Xuereb, A. de Oliveira Junior·Aug 21, 2026
The heat capacity of a system quantifies how it energetically responds to changes in temperature at equilibrium. Whilst this quantity is positive and even additive for non-interacting systems, self-gravitating systems such as stars or subsystems of s...
Classical versus non-classical photon states for detecting vacuum non-linearity
N. Ahmadiniaz, C. Kohlfürst, R. Shaisultanov +1 more·Aug 21, 2026
Quantum electrodynamics (QED) predicts that the vacuum should behave as a non-linear medium. For many schemes aimed at verifying this fundamental prediction, the signal consists of one or more photons in a certain mode (determined by polarization $σ$...
