Coherence-induced deep thermalization transition in random permutation quantum dynamics
Chang Liu, Matteo Ippoliti, Wen Wei Ho·Oct 21, 2025
We report a phase transition in the projected ensemble - the collection of post-measurement wavefunctions of a local subsystem obtained by measuring its complement. The transition emerges in systems undergoing random permutation dynamics, a type of q...
Entanglement Spectrum Resolved by Loop Symmetries
Haruki Yagi, Zongping Gong·Oct 21, 2025
A rigorous analysis is presented for the entanglement spectrum of quantum many-body states possessing a higher-form group-representation symmetry generated by topological Wilson loops, which is generally non-invertible. A general framework based on e...
Information geometry of nonmonotonic quantum natural gradient
Hideyuki Miyahara·Oct 21, 2025
Natural gradient is an advanced optimization method based on information geometry, where the Fisher metric plays a crucial role. Its quantum counterpart, known as quantum natural gradient (QNG), employs the symmetric logarithmic derivative (SLD) metr...
Quantum improved wormholes in the Dekel-Zhao dark matter halo
Jonathan A. Rebouças, Celio R. Muniz, Francisco Bento Lustosa +1 more·Oct 21, 2025
This work presents and investigates novel traversable wormhole solutions within the framework of Asymptotically Safe Gravity (ASG), sourced by a dark matter halo modeled by the Dekel--Zhao density profile. The scale-dependent gravitational coupling $...
Near-optimal Prediction Error Estimation for Quantum Machine Learning Models
Qiuhao Chen, Yuling Jiao, Yinan Li +2 more·Oct 21, 2025
Understanding the theoretical capabilities and limitations of quantum machine learning (QML) models to solve machine learning tasks is crucial to advancing both quantum software and hardware developments. Similarly to the classical setting, the perfo...
Burau representation, Squier's form, and non-Abelian anyons
Alexander Kolpakov·Oct 21, 2025
We introduce a frequency-tunable, two-dimensional non-Abelian control of operation order constructed from the reduced Burau representation of the braid group $B_3$, specialised at $t=e^{iω}$ and unitarized by Squier's Hermitian form. Coupled to two n...
Basis-Sensitive Quantum Typing via Realisability
Alejandro D'iaz-Caro, Octavio Malherbe, Rafael Romero·Oct 21, 2025
We present $\lambda_B$, a quantum-control $\lambda$-calculus that refines previous basis-sensitive systems by allowing abstractions to be expressed with respect to arbitrary -- possibly entangled -- bases. Each abstraction and let construct is annota...
Chiral light from an emitter coupled to an achiral particle via the Purcell effect
Yining Xuan, Daito Miyazaki, Yuki Ishikawa +1 more·Oct 20, 2025
We demonstrate that non-chiral nanoparticles can produce chiral light when point emitters are coupled to their surface plasmon modes (SPMs) under certain conditions. Chiral emission arises from asymmetrical plasmon mode propagation from the source co...
A Quantum Algorithm for the Finite Element Method
Ahmad M. Alkadri, Tyler D. Kharazi, K. Birgitta Whaley +1 more·Oct 20, 2025
The finite element method (FEM) is a cornerstone numerical technique for solving partial differential equations (PDEs). Here, we present $\textbf{Qu-FEM}$, a fault-tolerant era quantum algorithm for the finite element method. In contrast to other qua...
Quantum-Assisted Barrier Sequential Quadratic Programming for Nonlinear Optimal Control
Nahid Binandeh Dehaghani, Rafal Wisniewski, A. Pedro Aguiar·Oct 20, 2025
We propose a quantum-assisted framework for solving constrained finite-horizon nonlinear optimal control problems using a barrier Sequential Quadratic Programming (SQP) approach. Within this framework, a quantum subroutine is incorporated to efficien...
Incomplete yet existent objects: a Nuclear Meinongian approach to quantum metaphysical indeterminacy
Raoni Arroyo, Renato Semaniuc Valvassori·Oct 20, 2025
This article proposes a reading of quantum metaphysical indeterminacy from the perspective of Parsons' Nuclear Meinongianism. In doing so, we identify a fundamental incompatibility between a key feature of Parsons' theory and standard quantum mechani...
Virus Spreading in Quantum Networks
Junpeng Hou, Mark M. Seidel, Chuanwei Zhang·Oct 20, 2025
Recent advances in quantum communication have enabled long-distance secure information transfer through quantum channels, giving rise to quantum networks with unique physical and statistical properties. However, as in classical networks, the propagat...
Quantum Computing Approach to Atomic and Molecular Three-Body Systems
Mohammad Haidar, Hugo D. Nogueira, J. -Ph. Karr·Oct 20, 2025
We present high-precision quantum computing simulations of three-body atoms (He, H$^-$) and molecules (H$_2^+$, HD$^+$), the latter being studied beyond the Born-Oppenheimer approximation. The Non-Iterative Disentangled Unitary Coupled Cluster Variat...
Application Scale Quantum Circuit Compilation with Controlled Error
Justin Kalloor, Lucas Kovalsky, Mathias Weiden +4 more·Oct 20, 2025
Compilation and optimization of quantum circuits are critical components in the execution of algorithms on quantum computers. These components must successfully balance two competing priorities: minimizing the number of expensive resources, such as t...
QINNs: Quantum-Informed Neural Networks
Aritra Bal, Markus Klute, Benedikt Maier +3 more·Oct 20, 2025
Classical deep neural networks can learn rich multi-particle correlations in collider data, but their inductive biases are rarely anchored in physics structure. We propose quantum-informed neural networks (QINNs), a general framework that brings quan...
Interplay of Noise and Reservoir-induced Decoherence in Persistent Currents
Samudra Sur, Thierry Giamarchi·Oct 20, 2025
Persistent current is a hallmark of quantum phase coherence. We study the fate of the persistent current in a non-equilibrium setting, where a tight-binding ring is subjected to stochastic disorder as well as a fermionic reservoir attached to each si...
