Reducing Ion Heating in Quantum Computing: A Novel 3D-Printed Micro Ion Trap with Skeleton Structure
Chon-Teng Belmiro Chu, Hao-Chung Chen, Ting Hsu +3 more·Oct 26, 2025
Electric-field-induced ion heating is a major obstacle in scalable trapped-ion quantum computing. We present a theoretical study of a novel 3D-printed ion trap with a skeleton electrode structure, designed to reduce heating by minimizing surface area...
Scalable Neural Decoders for Practical Real-Time Quantum Error Correction
Changwon Lee, Tak Hur, Daniel K. Park·Oct 26, 2025
Real-time, scalable, and accurate decoding is a critical component for realizing a fault-tolerant quantum computer. While Transformer-based neural decoders such as \textit{AlphaQubit} have demonstrated high accuracy, the computational complexity of t...
Generation and Detection of Hyperentangled Bell States at an Ultra-High Flux
Netanel P. Yaish, Samata Gokhale, Avi Peer·Oct 26, 2025
We demonstrate both the generation and detection of an ultra-high flux of polarization Bell states using broadband hyper-entangled bi-photons that are quantum-correlated in both polarization and time-energy. Bell states of polarization embody the mos...
The Gravitational Aspect of Information: The Physical Reality of Asymmetric "Distance"
Tomoi Koide, Armin van de Venn·Oct 26, 2025
We show that when a Brownian bridge is physically constrained to satisfy a canonical condition, its time evolution exactly coincides with an m-geodesic on the statistical manifold of Gaussian distributions. This identification provides a direct physi...
Toward Krylov-based holography in double-scaled SYK
Yichao Fu, Hyun-Sik Jeong, Keun-Young Kim +1 more·Oct 26, 2025
Building on the duality between Krylov complexity and geodesic length in Jackiw-Teitelboim and sine-dilaton gravity, we develop a precise holographic dictionary for quantities in the Krylov subspace of the double-scaled Sachdev-Ye-Kitaev model (DSSYK...
Quantum Information Meets High-Energy Physics: Probing Neutrinos and Beyond
Raoul Serao, Gianpaolo Torre, Antonio Capolupo·Oct 26, 2025
This review explores the interplay between quantum information theory and high-energy physics, emphasizing how decoherence effects and unconventional neutrino oscillation patterns may unveil fundamental properties such as the Dirac or Majorana nature...
Enabling Shortwave-QKD in Short-Reach Networks: Impact of a Composite ODN Native to Telecom Applications
Mariana F. Ramos, Costin Luchian, Michael Hentschel +4 more·Oct 26, 2025
We deploy shortwave-QKD over short-reach in-house/datacom architectures and show that few-mode propagation and speckle-selective loss severely impact the QKD performance. We accomplish 12 kb/s secure-key generation in presence of 50 co-existing data ...
Sensitive detection of the Rydberg transition in trapped electrons on liquid helium using radio-frequency reflectometry
Jui-Yin Lin, Tomoyuki Tani, Mikhail Belianchikov +1 more·Oct 26, 2025
Radio-frequency reflectometry, which probes small changes in the electrical impedance of a device, provides a useful method for sensitive and fast detection of dynamic processes in quantum systems. We use this method to detect excitation of the quant...
Quantum Bit Threads and the Entropohedron
Matthew Headrick, Sreeman Reddy Kasireddy, Andrew Rolph·Oct 26, 2025
We derive several new quantum bit thread prescriptions for holographic entanglement entropy, equivalent for static states to the quantum extremal surface formula. Our new prescriptions come in many varieties: vector field-based or based on measures o...
Open harmonic chain without secular approximation
Melika Babakan, Fabio Benatti, Laleh Memarzadeh·Oct 26, 2025
We study particle and energy transport in an open quantum system consisting of a three harmonic oscillator chain coupled to thermal baths at different temperatures placed at the ends of the chain. We consider the exact dynamics of the open chain and ...
The Thermodynamics of the Gravity from Entropy Theory
Ginestra Bianconi·Oct 26, 2025
The Gravity from Entropy (GfE) action posits that gravity that is fundamentally given by the information encoded in the interplay between matter and geometry. The GfE Lagrangian is given by the Geometric Quantum Relative Entropy (GQRE) between the ph...
Krylov Complexity and Mixed-State Phase Transition
Hung-Hsuan Teh, Takahiro Orito·Oct 26, 2025
We establish a unified framework connecting decoherence and quantum complexity. By vectorizing the density matrix into a pure state in a double Hilbert space, a decoherence process is mapped to an imaginary-time evolution. Expanding this evolution in...
qc-kmeans: A Quantum Compressive K-Means Algorithm for NISQ Devices
Pedro Chumpitaz-Flores, My Duong, Ying Mao +1 more·Oct 26, 2025
Clustering on NISQ hardware is constrained by data loading and limited qubits. We present \textbf{qc-kmeans}, a hybrid compressive $k$-means that summarizes a dataset with a constant-size Fourier-feature sketch and selects centroids by solving small ...
Experimental Proposal on Scalable Radio-Frequency Magnetometer with Trapped Ions
Yuxiang Huang, Wei Wu, Qingyuan Mei +1 more·Oct 26, 2025
Quantum magnetometry represents a fundamental component of quantum metrology, where trapped-ion systems have achieved $\rm{pT}/\sqrt{\rm{Hz}}$ sensitivity in single-ion radio-frequency magnetic field measurements via dressed states based dynamical de...
An Analytic Theory of Quantum Imaginary Time Evolution

Quantum imaginary time evolution (QITE) algorithm is one of the most promising variational quantum algorithms (VQAs), bridging the current era of Noisy Intermediate-Scale Quantum devices and the future of fully fault-tolerant quantum computing. Altho...
Single-photon superradiance and subradiance in helical collectives of quantum emitters
Hamza Patwa, Philip Kurian·Oct 26, 2025
Collective emission of light from distributions of two-level systems (TLSs) was first predicted in 1954 by Robert Dicke, who showed that when $N$ quantum emitters absorb photons, their collective radiative decay rate can be enhanced (superradiance) o...

Eugene V. Sukhorukov, Adrien Tomà·Oct 25, 2025
We develop a unified perturbative framework for energy transport along a chiral quantum Hall edge coupled to a disordered, compressible strip. Treating the strip as a generic linear response environment characterized by its retarded susceptibility, w...
