Onsiteability of Higher-Form Symmetries
Yitao Feng, Yu-An Chen, Po-Shen Hsin +1 more·Oct 27, 2025
An internal symmetry in a lattice model is said to be onsiteable if it can be disentangled into an onsite action by introducing ancillas and conjugating with a finite-depth circuit. A standard lore holds that onsiteability is equivalent to being anom...
Gaussian tomography for cold-atom simulators
Matthew Kiser, Max McGinley, Daniel Malz·Oct 27, 2025
A limitation of analog quantum simulators based on cold atoms in optical lattices is that readout is typically limited to observables diagonal in the charge basis, i.e., densities and density correlation functions. To overcome this limitation, we pro...
Can Newtonian Gravity Produce Quantum Entanglement?
Feng-Li Lin, Sayid Mondal·Oct 27, 2025
We investigate whether Newtonian gravity can generate quantum entanglement between mesoscopic quantum bodies modeled as superposed mass quadrupoles using three complementary approaches: mini-superspace, semiclassical gravity, and stochastic gravity. ...
FPGA-Based Adaptive Control for Phase Stabilization in Fiber-Optic Interferometers Using Correlated Photons
P. M. Berto, F. CampodÓnico, A. A. Matoso +5 more·Oct 27, 2025
Time-bin encoded photon pairs enable robust, decoherence-resistant transmission through optical fibers for long-distance quantum communication, where phase noise poses a critical limitation to stable operation. Here, we implement an adaptive Perturba...
Variational Thermal State Preparation on Digital Quantum Processors Assisted by Matrix Product States
Rui-Hao Li, Semeon Valgushev, Khadijeh Najafi·Oct 27, 2025
The preparation of quantum Gibbs states at finite temperatures is a cornerstone of quantum computation, enabling applications in quantum simulation of many-body systems, machine learning via quantum Boltzmann machines, and optimization through therma...
The Enigma of Delayed Choice Quantum Eraser
Tabish Qureshi·Oct 27, 2025
The delayed-choice quantum eraser represents an interesting experiment that exemplifies Bohr's principle of complementarity in a beautiful way. According to the complementarity principle, in a two-path interference experiment, the knowledge of which ...
Architecting Scalable Trapped Ion Quantum Computers using Surface Codes
Scott Jones, Prakash Murali·Oct 27, 2025
Trapped ion (TI) qubits are a leading quantum computing platform. Current TI systems have less than 60 qubits, but a modular architecture known as the Quantum Charge-Coupled Device (QCCD) is a promising path to scale up devices. There is a large gap ...
Quantum Phase Classification of Rydberg Atom Systems Using Resource-Efficient Variational Quantum Circuits and Classical Shadows
Hemish Ahuja, Samradh Bhardwaj, Kirti Dhir +2 more·Oct 27, 2025
Quantum phase transitions in Rydberg atom arrays present significant opportunities for studying many-body physics, yet distinguishing between different ordered phases without explicit order parameters remains challenging. We present a resource-effici...
Bound entanglement in symmetric random induced states
Jonathan Louvet, François Damanet, Thierry Bastin·Oct 27, 2025
Bound entanglement, a weak -- yet resourceful -- form of quantum entanglement, remains notoriously hard to detect and construct. We address this in this paper by leveraging symmetric random induced states, where positive partial transpose (PPT) bound...
SQOUT: A Risk-Based Threat Analysis Framework for Quantum Communication Systems
Michal Krelina, Tom Sorger, Bob Dirks·Oct 27, 2025
This paper addresses the urgent need for a cybersecurity framework tailored to quantum communication systems as the world transitions to quantum-safe infrastructures. While quantum communication promises unbreakable security, real-world deployments a...
Anti-Flatness and Non-Local Magic in Two-Particle Scattering Processes
C. E. P. Robin, M. J. Savage·Oct 27, 2025
Non-local magic and anti-flatness provide a measure of the quantum complexity in the wavefunction of a physical system. Supported by entanglement, they cannot be removed by local unitary operations, thus providing basis-independent measures, and suff...
Probabilistic Computing Optimization of Complex Spin-Glass Topologies
Fredrik Hasselgren, Max O. Al-Hasso, Amy Searle +2 more·Oct 27, 2025
Spin glass systems as lattices of disordered magnets with random interactions have important implications within the theory of magnetization and applications to a wide-range of hard combinatorial optimization problems. Nevertheless, despite sustained...
Free-space quantum interface of a single atomic tweezer array with light
Yakov Solomons, Roni Ben-Maimon, Arpit Behera +3 more·Oct 27, 2025
We present a practical approach for interfacing light with a two-dimensional atomic tweezer array. Typical paraxial fields are poorly matched to the array's multi-diffraction-order radiation pattern, thus severely limiting the interface coupling effi...
Sustainable NARMA-10 Benchmarking for Quantum Reservoir Computing
Avyay Kodali, Priyanshi Singh, Pranay Pandey +3 more·Oct 27, 2025
This study compares Quantum Reservoir Computing (QRC) with classical models such as Echo State Networks (ESNs) and Long Short-Term Memory networks (LSTMs), as well as hybrid quantum-classical architectures (QLSTM), for the nonlinear autoregressive mo...
Binary gravitational waves as probes of quantum graviton states
Sugumi Kanno, Jiro Soda, Akira Taniguchi·Oct 27, 2025
It is well known that the most reliable way to reveal the quantum nature of light is through photon number statistics, since photons exhibiting sub-Poissonian statistics unambiguously demonstrate their quantum behavior. In this paper, we show that gr...
Estimating applied potentials in cold atom lattice simulators
Bhavik Kumar, Daniel Malz·Oct 27, 2025
Cold atoms in optical lattices are a versatile and highly controllable platform for quantum simulation, capable of realizing a broad family of Hubbard models, and allowing site-resolved readout via quantum gas microscopes. In principle, arbitrary sit...
Chaos in Systems with Quantum Group Symmetry
Victor Gorbenko, Aleksandr Zhabin·Oct 27, 2025
Quantum groups have a long and fruitful history of applications in integrable systems. Can quantum group symmetries exist in the absence of integrability? We provide an explicit example of a system with quantum group global symmetry which is chaotic....
Robust Iterative Learning Hidden Quantum Markov Models
Ning Ning·Oct 27, 2025
Hidden Quantum Markov Models (HQMMs) extend classical Hidden Markov Models to the quantum domain, offering a powerful probabilistic framework for modeling sequential data with quantum coherence. However, existing HQMM learning algorithms are highly s...
Spoofing resilience for simple-detection quantum illumination LIDAR
Richard J. Murchie, John Jeffers·Oct 27, 2025
Object detection and range finding using a weak light source is vulnerable to jamming and spoofing attacks by an intruder. Quantum illumination with nonsimultaneous, phase-insensitive coincidence measurements can provide jamming resilience compared t...
Rabi oscillations of a monolayer quantum emitter driven through its excited state
Victor N. Mitryakhin, Ivan A. Solovev, Alexander Steinhoff +5 more·Oct 27, 2025
The interaction of a quantum two-level system with a resonant driving field results in the emergence of Rabi oscillations, which are the hallmark of a controlled manipulation of a quantum state on the Bloch sphere. This all-optical coherent control o...
