Quantum predator-prey cycles in dissipative Rydberg lattices

Ya-Xin Xiang, Zhengyang Bai, Yu-Qiang Ma·Oct 30, 2025

The Lotka-Volterra model is a paradigm for self-organized predator-prey oscillations in far-from-equilibrium systems, yet testing it in real-world ecosystems is hindered by uncontrollable microscopic parameters. Here, we propose a quantum analogue of...

Single-Light-Pulse Driven Compact Atom Interferometry with Measurement Induced Large Momentum Transfer

Yinghang Jiang, Jiguo Wu, Junfan Zhu +2 more·Oct 30, 2025

We propose a fundamentally new design strategy of light-pulsed atom interferometry (LPAI) with a single atomic beam splitter. A traditional $π/2$-pulse Raman beam is employed to render a small momentum transfer at the initial state. After a short per...

Overcoming disorder in superconducting globally driven quantum computing

Riccardo Aiudi, Julien Despres, Roberto Menta +5 more·Oct 29, 2025

We study the impact of static disorder on a globally-controlled superconducting quantum computing architecture based on a quasi-two-dimensional ladder geometry [R. Menta et al., Phys. Rev. Research 7, L012065 (2025)]. Specifically, we examine how fab...

Dynamics of entanglement fluctuations and quantum Mpemba effect in the $ν=1$ QSSEP model

Angelo Russotto, Filiberto Ares, Pasquale Calabrese +1 more·Oct 29, 2025

We study the out-of-equilibrium dynamics of entanglement fluctuations in the $ν=1$ Quantum Symmetric Simple Exclusion Process, a free-fermion chain with hopping amplitudes that are stochastic in time but homogeneous in space. Previous work showed tha...

Group Representations of Lorentz Transformations Extended to Superluminal Observers

Marco Zaopo·Oct 29, 2025

We construct an extension of the proper orthochronous Lorentz group that includes space-time transformations for observers moving with superluminal relative velocities in arbitrary direction. This extension is generated by a realization of the Klein ...

Imaginarity measures induced by real part states and the complementarity relations

Jingyan Liu, Yue Sun, Jianwei Xu +1 more·Oct 29, 2025

Complex numbers are indispensable in quantum mechanics and the resource theory of imaginarity has been developed recently. In this paper, we propose a method to construct imaginary measures by real part states. Specifically, we propose an imaginarity...

Statistical mechanics from quantum envariance and exchange symmetry

Amul Ojha, Shubhit Sardana, Arnab Ghosh·Oct 29, 2025

We build on the foundational work of Deffner and Zurek [S. Deffner and W. H. Zurek, New J. Phys. 18, 063013 (2016)] to show how central equilibrium structures of statistical mechanics can be understood within standard quantum mechanics using the conc...

Pairing-induced phase transition in the non-reciprocal Kitaev chain

Pietro Brighi, Andreas Nunnenkamp·Oct 28, 2025

Investigating the robustness of non-reciprocity in the presence of competing interactions is central to understanding non-reciprocal quantum matter. In this work, we use reservoir engineering to induce non-reciprocal hopping and pairing in the fermio...

Bounds on Lorentz-violating parameters in magnetically confined 2D systems: A phenomenological approach

Edilberto O. Silva·Oct 28, 2025

We present a unified, SI-consistent framework to constrain minimal SME coefficients $a_μ$ and $b_μ$ using magnetically confined two-dimensional electron systems under a uniform magnetic field. Working in the nonrelativistic (Schrödinger--Pauli) limit...

Free-Fermion Measurement-Induced Volume- to Area-Law Entanglement Transition in the Presence of Fermion Interactions

Matthew S. Foster, Haoyu Guo, Chao-Ming Jian +1 more·Oct 27, 2025

At a generic volume- to area-law entanglement transition in a many-body system, quantum chaos is arrested. We argue that this tends to imply the vanishing of a certain "mass" term in the field theory of the measurement-induced phase transition (MIPT)...

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. ...

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...

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...

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...
