ECMSim: A high-performance interactive web application for real-time spatiotemporal simulation of cardiac ECM signaling and diffusion
Hasi Hays, William J. Richardson·Oct 14, 2025
Extracellular matrix (ECM) remodeling is central to a wide variety of healthy and diseased tissue processes. Unfortunately, predicting ECM remodeling under various chemical and mechanical conditions has proven to be excessively challenging, due in pa...
Snapshot renormalization group for quantum matter
Laurin Brunner, Tobias Wiener, Tiago Mendes-Santos +2 more·Oct 14, 2025
Recent advances in quantum simulator experiments enable unprecedented access to quantum many-body states through snapshot measurements of individual many-body configurations. Here, we introduce an exact renormalization group (RG) transformation that ...
Efficient Preparation of Quantum States via Randomized Truncation
Yue Wang, Xiao-Ming Zhang, Xiao Yuan +1 more·Oct 14, 2025
While the preparation of a general quantum state is challenging, realistic problem instances, such as those encountered in quantum chemistry and quantum machine learning-typically exhibit hierarchical amplitude structures, consisting of a small numbe...
Digital adiabatic evolution is universally accurate
Yangyu Lu, Yifei Huang, Dong An +3 more·Oct 14, 2025
Adiabatic evolution is a central paradigm in quantum physics. Digital simulations of adiabatic processes are generally viewed as costly, since algorithmic errors typically accumulate over the long evolution time, requiring exceptionally deep circuits...
Superradiance and Superabsorption Engine of $N$ Two-Level Systems: $N^{2}$-Power Scaling at Near-Unity Efficiency
L. F. Alves da Silva, H. Sanchez, M. A. Ponte +2 more·Oct 13, 2025
We present a thermal engine that exploits the \emph{cooperative superradiance} and \emph{superabsorption} of a sample of \(N\) two-level atoms. This engine operates using a single cold reservoir via cycles of collective pumping followed by decay. Usi...
Qiboml: towards the orchestration of quantum-classical machine learning
Matteo Robbiati, Andrea Papaluca, Andrea Pasquale +12 more·Oct 13, 2025
We present Qiboml, an open-source software library for orchestrating quantum and classical components in hybrid machine learning workflows. Building on Qibo's quantum computing capabilities and integrating with popular machine learning frameworks suc...
The Magic Barrier before Thermalization
Lukas Ebner, Berndt Müller, Andreas Schäfer +3 more·Oct 13, 2025
We investigate the time dependence of anti-flatness in the entanglement spectrum, a measure for non-stabilizerness and lower bound for non-local quantum magic, on a subsystem of a linear SU(2) plaquette chain during thermalization. Tracing the time e...
Observation of ballistic plasma and memory in high-energy gauge theory dynamics
Daniel K. Mark, Federica M. Surace, Thomas Schuster +4 more·Oct 13, 2025
Gauge theories describe the fundamental forces of nature. However, high-energy dynamics, such as the formation of quark-gluon plasmas, is notoriously difficult to model with classical methods. Quantum simulation offers a promising alternative in this...
A Monte Carlo approach to bound Trotter error
Nick S. Blunt, Aleksei V. Ivanov, Andreas Juul Bay-Smidt·Oct 13, 2025
Trotter product formulas are a natural and powerful approach to perform quantum simulation. However, the error analysis of product formulas is challenging, and their cost is often overestimated. It is established that Trotter error can be bounded in ...
Telecom-compatible cross-band quantum memory via dual photon modes dark-state polaritons
Dounan Du, Eden Figueroa·Oct 13, 2025
Quantum memories are essential components of quantum networks, enabling synchronization, quantum repeaters, and long-distance entanglement distribution. Most ensemble-based realizations rely on dark-state polaritons (DSPs) in $Λ$-type systems that op...
Astigmatism-free 3D Optical Tweezer Control for Rapid Atom Rearrangement
Yue-Hui Lu, Nathan Song, Tai Xiang +4 more·Oct 13, 2025
Reconfigurable arrays of neutral atoms are a leading platform for quantum computing, quantum simulation, and quantum metrology. The most common method for atom reconfiguration using optical tweezers relies on frequency chirping of acousto-optic defle...
Tensor-Network-Based Unraveling of Non-Markovian Dynamics in Large Spin Chains via the Influence Martingale Approach
Sujay Mondal, Siddhartha Dutta, Abhijit Bandyopadhyay·Oct 13, 2025
Classical simulation of open quantum system dynamics remains challenging due to the exponential growth of the Hilbert space, the need to accurately capture dissipation and decoherence, and the added complexity of memory effects in the non-Markovian r...
Analytical Control of Quantum Coherence: Markovian Revival via Basis Engineering and Exact Non-Markovian Criteria
Na-Na Zhang, Chao-Yi Wu, Ming Li +4 more·Oct 13, 2025
The preservation of quantum coherence is besieged by a fundamental dogma: its revival necessitates non-Markovian memory effects from structured environments. This paradigm has constrained quantum control strategies and obscured simpler paths to coher...
On the Feasibility of Exact Unitary Transformations for Many-body Hamiltonians
Praveen Jayakumar, Tao Zeng, Artur F. Izmaylov·Oct 13, 2025
Exact unitary transformations play a central role in the analysis and simulation of many-body quantum systems, yet the conditions under which they can be carried out exactly and efficiently remain incompletely understood. We show that exact transform...
Dominant spin-spin relaxation mechanism at clock transition of the $Ho_{x}Y_{1-x}W_{10}$ complex at different concentrations
Xiao Chen, Haechan Park, Silas Hoffman +2 more·Oct 13, 2025
Spin decoherence poses a significant challenge in molecular magnets, with the nuclear spin bath serving as a prominent source. Intriguingly, spin qubits at the clock transition exhibit remarkable insensitivity to the surrounding nuclear spins. Recent...
