A Lyapunov Framework for Quantum Algorithm Design in Combinatorial Optimization with Approximation Ratio Guarantees
Shengminjie Chen, Ziyang Li, Hongyi Zhou +3 more·Dec 25, 2025
In this work, we develop a framework aiming at designing quantum algorithms for combinatorial optimization problems while providing theoretical guarantees on their approximation ratios. The principal innovative aspect of our work is the construction ...
Investigation of quantum chaos in local and non-local Ising models
Reza Pirmoradian, Elham Sadoogh, Maryam Teymouri +3 more·Dec 25, 2025
We investigate signatures of quantum chaos within Ising spin chains subjected to transverse and longitudinal fields, incorporating both local (nearest-neighbor) and non-local (long-range) couplings. While local Ising models may exhibit integrable or ...
GaDE -- GPU-acceleration of time-dependent Dirac Equation for exascale
Johanne Elise Vembe, Marcin Krotkiewski, Magnar Bjørgve +2 more·Dec 25, 2025
Modern heterogeneous high-performance computing (HPC) systems powered by advanced graphics processing unit (GPU) architectures enable accelerating computing with unprecedented performance and scalability. Here, we present a GPU-accelerated solver for...
On prethermal time crystals from semi-holography
Toshali Mitra, Sukrut Mondkar, Ayan Mukhopadhyay +1 more·Dec 25, 2025
We demonstrate the existence of a pair of almost dissipationless oscillating modes at low temperatures in both the shear and sound channels of a hybrid quantum system, comprised of a weakly self-interacting perturbative sector coupled to strongly sel...
Asymmetric polaron picture for the quantum Rabi model
Feng Qiao, Qiu-Yi Chen, Zu-Jian Ying·Dec 25, 2025
The experimental access to ultra-strong couplings in light-matter interactions has made the quantum phase transition (QPT) in the quantum Rabi model practically relevant, while the physics of the QPT has not yet been fully explored. The polaron pictu...
Insufficiency of Pure-State Ensembles in Characterizing Transformations of Entangled States under LOCC
C. L. Liu, Baoqing Sun, D. L. Zhou·Dec 25, 2025
The conditions for transforming pure entangled states under local operations and classical communication (LOCC) are well understood. A natural question then arises: Can we determine the transformation conditions for mixed entangled states under LOCC ...
Spectroscopic Search for Topological Protection in Open Quantum Hardware: The Dissipative Mixed Hodge Module Approach
Prasoon Saurabh·Dec 25, 2025
Standard spectroscopic protocols model the dynamics of open quantum systems as a superposition of isolated, exponentially decaying eigenmodes. This paradigm fails fundamentally at Exceptional Points, where the eigenbasis collapses and the response be...
Trade-off relation between integrated metrological gain and local dissipation in magnetic-field sensing by quantum spin ensemble
Nozomu Takahashi, Le Bin Ho, Hiroaki Matsueda·Dec 25, 2025
Quantum metrology plays a central role in precision sensing, where quantum enhancement of detection performance is crucial for both fundamental studies and practical applications. In this work, we derive a tight performance bound for magnetic-field s...
Hybrid Quantum Repeater Chains with Atom-based Quantum Processing Units and Quantum Memory Multiplexers
Shin Sun, Daniel Bhatti, Shaobo Gao +2 more·Dec 25, 2025
Quantum repeaters enable the generation of reliable entanglement across long distances despite the underlying channel noise. Nevertheless, realizing quantum repeaters poses a difficult engineering challenge due to various device constraints and desig...
Waveguide-array-based multiplexed photonic interface for atom array
Yuya Maeda, Toshiki Kobayashi, Takuma Ueno +12 more·Dec 25, 2025
The growing demand for high-capacity quantum communication and large-scale quantum computing underscores the importance of networking quantum processing units via multiplexed photonic channels. A neutral atom array with multiplexed atom-photon entang...
Quantum Mean-Fields Spin Systems in a Random External Field
Chokri Manai·Dec 25, 2025
In this work, we consider general exchangeable quantum mean-field Hamiltonian such as the prominent quantum Curie-Weiss model under the influence of a random external field. Despite being arguably the simplest class of disordered quantum systems, the...
Quantum Nondecimated Wavelet Transform: Theory, Circuits, and Applications
Brani Vidakovic·Dec 25, 2025
The nondecimated or translation-invariant wavelet transform (NDWT) is a central tool in classical multiscale signal analysis, valued for its stability, redundancy, and shift invariance. This paper develops two complementary quantum formulations of th...
Topological guidance of a self-propelled particle
Ethan Andersson, Valeri Frumkin·Dec 25, 2025
Topological phenomena typically govern the behavior of delocalized waves, giving rise to robust transport in electronic, photonic, and mechanical systems. Whether similar principles can directly control the motion of a localized particle, particularl...
Electrical Control of Optically Active Single Spin Qubits in ZnSe
Amirehsan Alizadehherfati, Yuxi Jiang, Nils von den Driesch +6 more·Dec 25, 2025
Electrons bound to shallow donors in ZnSe quantum wells are promising candidates for optically addressable spin qubits and single-photon sources. However, their optical coherence and indistinguishability are often limited by spectral broadening arisi...
Algebraic Fusion in a (2+1)-dimensional Lattice Model with Generalized Symmetries
Chinmay Giridhar, Philipp Vojta, Zohar Nussinov +2 more·Dec 24, 2025
The notion of quantum symmetry has recently been extended to include reduced-dimensional transformations and algebraic structures beyond groups. Such generalized symmetries lead to exotic phases of matter and excitations that defy Landau's original p...

We report high-precision frequency ratio measurements between optical atomic clocks based on $^{27}$Al$^+$, $^{171}$Yb, and $^{87}$Sr. With total fractional uncertainties at or below $3.2 \times 10^{-18}$, these measurements meet an important milesto...
Asymptotic Momentum of Dirac Particles in One Space Dimension
Kabir Narayanan, Abigail Perryman, A. Shadi Tahvildar-Zadeh·Dec 24, 2025
We analyze the trajectories of a massive particle in one space dimension whose motion is guided by a spin-half wave function that evolves according to the free Dirac equation, with its initial wave function being a Gaussian wave packet with a nonzero...
Observation of disorder-induced superfluidity
Nicole Ticea, Elias Portoles, Eliott Rosenberg +299 more·Dec 24, 2025
The emergence of states with long-range correlations in a disordered landscape is rare, as disorder typically suppresses the particle mobility required for long-range coherence. But when more than two energy levels are available per site, disorder ca...
