Phase-Stable Hologram Updates for Large-Scale Neutral-Atom Array Reconfiguration
Erdong Huang, Jiayi Huang, Hongshun Yao +2 more·Apr 6, 2026
Assembling large-scale, defect-free Rydberg atom arrays is a key technology for neutral-atom quantum computation. Dynamic holographic optical tweezers enable the assembly and reconfiguration of such arrays, but phase mismatches between successive hol...
Circuit Harmonic Matrices: A Spectral Framework for Quantum Machine Learning
Kyle James Stuart Campbell, Luigi Del Debbio, Petros Wallden·Apr 5, 2026
Parametrised quantum circuits are a central framework for near term quantum machine learning. However, it remains challenging to determine in advance how architectural choices, such as encoding strategies, gate placement, and entangling structure, in...
Quantization of Lagrangian Descriptors
Javier Jiménez-López, V. J. García-Garrido·Apr 5, 2026
We formulate Lagrangian descriptors (LDs) in the path integral framework. Averaging the classical LD over fluctuations about extremal trajectories defines a quantum LD that incorporates quantum effects. Invariant manifolds, which sharply organize cla...
Robust Universal Photon Blockade in a Bimodal Jaynes-Cummings Model via Kerr Nonlinearity
Guohao Chang, Hunduz Halemjan, Shangyun Liu +2 more·Apr 4, 2026
Universal photon blockade in a two-mode Jaynes-Cummings model incorporating third-order Kerr nonlinearity is demonstrated with a single two-level atom coupled to a waveguide microcavity. Realization of this universal photon blockade is attributed to ...
Entanglement generation from gravitationally produced massless vector particles during inflation
Alessio Belfiglio, Mattia Dubbini, Orlando Luongo·Apr 4, 2026
We study the gravitational production of spectator massless vector particles in a single-field inflationary scenario, and the related entanglement generation across the Hubble horizon. Accordingly, we consider a quasi-de Sitter background evolution, ...
Interaction with the Environment via Random Matrices and the Emergence of Classical Field Theory
Alexey A. Kryukov·Apr 4, 2026
It was recently shown that Newtonian dynamics of macroscopic particles can be derived from unitary Schrödinger evolution under an assumption on the system-environment interaction, namely that the interaction Hamiltonian effectively exhibits a random-...
Disorder-Induced Exponential Scaling of Subradiant Decay Rates
Guoqing Tian, Xin-You Lü·Apr 4, 2026
Subradiance, a hallmark cooperative phenomenon in waveguide QED, is characterized by a universal power-law scaling of decay rates with system size and underpins many applications in quantum information storage. Here, we demonstrate that disorder driv...
Post-Selection-Free Decoding of Measurement-Induced Area-Law Phases via Neural Networks
Hui Yu, Jiangping Hu, Shi-Xin Zhang·Apr 4, 2026
Monitored quantum circuits host a rich variety of exotic non-equilibrium phases. Among the most representative examples are measurement-induced phase transitions between distinct area-law entangled states. However, because these transitions are chara...
Non-reciprocal Ising gauge theory
Nilotpal Chakraborty, Anton Souslov, Claudio Castelnovo·Apr 3, 2026
Non-reciprocity and geometric frustration enable many-body systems to avoid crystalline order and instead exhibit complex, liquid-like behavior. Here we show that their interplay is richer than the sum of its parts, leading to surprising structural a...
Learning PDEs for Portfolio Optimization with Quantum Physics-Informed Neural Networks
Letao Wang, Abdel Lisser, Sreejith Sreekumar +1 more·Apr 3, 2026
Partial differential equations (PDEs) play a crucial role in financial mathematics, particularly in portfolio optimization, and solving them using classical numerical or neural network methods has always posed significant challenges. Here, we investi...
Computational framework for non-Markovian multi-emitter dynamics beyond the single-excitation limit
Hyunwoo Choi, Weng Cho Chew, Dong-Yeop Na·Apr 3, 2026
While non-Markovian dynamics have been extensively studied in the single-excitation limit to predict non-trivial phenomena, this regime remains an idealization. Moving beyond it is essential, as optical nonlinearities and phase-error accumulation in ...
Robust Correlation-Induced Localization Under Time-Reversal Symmetry Breaking
Bikram Pain, Sthitadhi Roy, Jens H. Bardarson +1 more·Apr 2, 2026
We study Anderson localization in a one-dimensional disordered system with long-range correlated hopping decaying as $1/r^{a}$ with complex hopping amplitudes that break time-reversal symmetry in a tunable fashion by varying their argument. We find a...
QuantumXCT: Learning Interaction-Induced State Transformation in Cell-Cell Communication via Quantum Entanglement and Generative Modeling
Selim Romero, Shreyan Gupta, Robert S. Chapkin +1 more·Apr 2, 2026
Inferring cell-cell communication (CCC) from single-cell transcriptomics remains fundamentally limited by reliance on curated ligand-receptor databases, which primarily capture co-expression rather than the system-level effects of signaling on cellul...
Q2NS Demo: A Quantum Network Simulator Based on ns-3
Francesco Mazza, Adam Pearson, Marcello Caleffi +1 more·Apr 2, 2026
Q2NS is an open-source quantum network simulator built on ns-3, the de facto standard for classical network simulation. By inheriting ns-3's mature classical stack and event-driven execution model, Q2NS enables faithful co-simulation of quantum-netwo...
Universal critical timescales in slow non-Hermitian dynamics
Giorgos Pappas, Diego Bautista Avilés, Luis E. F. Foa Torres +1 more·Apr 2, 2026
Non-Hermitian systems driven along slow parametric loops undergo non-adiabatic transitions whose outcome depends sensitively on the driving speed, yet no explicit formula has been available for the critical timescale $T_{\mathrm{cr}}$ at which these ...
Phase-enhanced nonreciprocal photon-phonon conversion via coupled optomechanical cavities
Divya Mishra, Parvendra Kumar·Apr 2, 2026
Nonreciprocity, characterized by direction-dependent signal propagation, is fundamental to technologies such as isolators, signal routing, and precision sensing. This letter theoretically demonstrates nonreciprocal phonon transport and the conversion...
Curvature-induced bound states in quantum wires
Tim Bergmann, Benjamin Schwager, Jamal Berakdar·Apr 2, 2026
A classical particle under spatial constraints is strictly confined to live on a specific space manifold or path, but this assumption is incompatible with the zero-point fluctuations of a quantum particle. One way to describe quantum mechanics under ...
Constructing Fermionic Dynamics with Closed Moment Hierarchies
A. E. Teretenkov·Apr 1, 2026
We construct a broad class of completely positive maps and Go\-rini--Kossakowski--Sudarshan-Lindblad generators for fermionic systems induced by linear transformations of system and environment modes. For these maps, we derive explicit Heisenberg-pic...
Dissipative Floquet engineering of gapped many-body phases using thermal baths
Lorenz Wanckel, André Eckardt·Apr 1, 2026
Floquet engineering, the control of a quantum system by means of time-periodic driving, allows to modify the properties of the system so that it becomes described by an approximate effective time-independent Hamiltonian. However, in the presence of i...
Thermal Entanglement and Out-of-Equilibrium Thermodynamics in 1D Bose gases
Julia Mathé, Nicky Kai Hong Li, Pharnam Bakhshinezhad +1 more·Apr 1, 2026
We investigate entanglement in and out of equilibrium in a one-dimensional Bose gas in its low-energy Bogoliubov regime. In this Gaussian setting, the state is fully characterized by its covariance matrix, which allows us to detect and quantify entan...
