Magneto-ionic control of topological transport in SrRuO3 via band topology engineering
Xuanchi Zhou, Xiaohui Yao, Xiaomei Qiao +5 more·Jun 20, 2026
The interplay between spin-orbit coupling (SOC) and nontrivial band topology in ferromagnets gives rise to a rich landscape of topological transport phenomena such as anomalous Hall effect (AHE) and topological Hall effect (THE). One central goal in ...
Fine-Tuning Large Language Models for Quantum Reasoning
Katherine Ip, Casey R. Myers, Udaya Parampalli +2 more·Jun 20, 2026
Large language models (LLMs) exhibit abilities beyond natural language modelling and text generation. Recent advances in their reasoning capabilities have spurred interest in applying LLMs to complex scientific tasks requiring deep domain expertise a...
Quantum Error Suppression via Symmetry-Averaged Virtual Distillation
Canyu He, Chunhua Zeng, Ruyu Yang +1 more·Jun 20, 2026
Reliable quantum simulation is limited by both algorithmic approximations and hardware noise, which usually coexist in the output of near-term and early fault-tolerant quantum devices. Existing error-suppression strategies often target these error so...
Acceleration of Free Electrons by Photonic Time-Crystals
Lior Bar-Hillel, Alexey Gorlach, Ido Kaminer +1 more·Jun 20, 2026
We study the quantum interaction between free electrons and photons in a time-varying media, and find that periodic modulation exponentially amplifies electron-photon coupling within momentum gaps, enabling arbitrarily large momentum transfer. By pre...
Quantifying and Probing Multipartite Entanglement via Minimum Entanglement Drop
Dong-Dong Dong, Xue-Ke Song, Liu Ye +1 more·Jun 20, 2026
Quantifying genuine multipartite entanglement remains a significant challenge. We propose a multipartite entanglement monotone defined by the minimum entanglement drop -- the reduction in global one-to-group entanglement upon tracing out a single par...
Entanglement, Discord, and Residual Coherence in Scalar-Induced Gravitational Waves
Waqas Ahmed·Jun 20, 2026
Scalar-induced gravitational waves are usually modeled as a classical stochastic background sourced by primordial curvature perturbations. We investigate whether residual quantum-information properties of the scalar sector can survive decoherence and...
Shuttling in Bidimensional Segmented Ion-Trap Quantum Processors with T-Junctions
J. Durandau, C. A. Brunet, F. Schmidt-Kaler +3 more·Jun 20, 2026
Shuttle-based trapped ion quantum processors typically employ a one-dimensional (1D) linear architecture to transport ion-qubits between one ore more laser interaction zones where the quantum gates are implemented, along with several qubit register s...
Demonstration of a Monolithic and Fully Telecom-Fiber-Compatible Tunable Source of Polarization Entangled Photon Pairs Based on a van der Waals Material
Benjamin Laudert, Fatemeh Abtahi, Duk Choi +2 more·Jun 20, 2026
We present a tunable, single-mode-optical-fiber-based source of polarization entangled photon pairs for the near-infrared telecommunication band that is deployable in standard infrastructure. The photon pairs are generated via spontaneous parametric ...
Dynamical Tipping in a Quantum Limit Cycle
Ya-Xin Xiang, Zhengyang Bai, Yu-Qiang Ma·Jun 20, 2026
Nonequilibrium systems maintain spatiotemporal order through energy dissipation and entropy production. Here, we demonstrate this principle by engineering a quantum limit cycle that emerges from the interplay between a first-order absorbing-state pha...
Quantum Memory in Scalar-Induced Gravitational Waves
Waqas Ahmed·Jun 20, 2026
Scalar-induced gravitational waves are usually treated as a classical stochastic background sourced by phase-random curvature perturbations. We show that this description can miss residual quantum information. Starting from a decohered two-mode Gauss...
Prethermal cooling with many-body quantum quenches
Jacob F. Steiner, Mohammad Hafezi, Stefan Kehrein +1 more·Jun 20, 2026
Many-body quantum quenches are typically associated with heating. In this work, we show that quantum quenches that perform positive work on the system can still lead to effective cooling of low-energy degrees of freedom if the quench energy is deposi...
Semi-Analytical Pricing for General Default Intensity Models
Ryan Parker, Mark Stedman, Luca Capriotti·Jun 19, 2026
Using the path-integral formalism, we develop an accurate and easy-to-compute semi-analytical approximation for a general class of {default intensity} models. We illustrate the accuracy of the method by presenting results for the Black-Karasinski mod...
First-Quantized Relativistic Quantum Simulation with Periodic and Dirichlet Boundary Conditions
Jeongho Bang, Timothy P. Spiller, Kyunghyun Baek +2 more·Jun 19, 2026
In this work, we present a methodology for first-quantized relativistic quantum simulation on one-dimensional finite domains under the two boundary conditions most commonly used in lattice models: periodic boundary conditions (PBC) and Dirichlet boun...
Solid-state transcapacitor, a new gain element for logic, memory and interconnects
Amrita Mathuriya, Roza Kotlyar, Neal Reynolds +9 more·Jun 19, 2026
Today's transistors dictate the voltage and charge scales for both logic and memory. While AI systems are recognized to be limited by memory energy, the dominant share of the energy is expended in the intrachip interconnects whose voltage and charge ...
Common causes for quantum identical particles
A. Hovhannisyan, S. Weigert, A. E. Allahverdyan·Jun 19, 2026
Violations of Bell's inequalities imply that joint probabilities generated by non-commutative measurements on two (non-identical) quantum particles do not have a single common cause. But joint probabilities generated for such non-identical particles ...
Dynamical Decoupling using Universal Optimal Tracking
Amit Devra, Emanuel Malvetti, Niklas J. Glaser +7 more·Jun 19, 2026
Dynamical decoupling (DD) is a widely used and resource-efficient technique for error suppression, but conventional DD relies on periodically repeating a short pulse block to refocus the qubit state during idle periods. Imperfections in this block ca...
Feedback-Controlled Magnon-Atom Entanglement and Photon Statistics
Yiping Lu, Yulong Hu, Zhuzheng Han +1 more·Jun 19, 2026
Quantum systems face inherent challenges in achieving precise control, and solving the Schrödinger equation is often intractable for complex hybrid platforms. Here, for the first time, we introduce a magnon into a feedback-controlled quantum system. ...
Configurable Algorithms for Histopathologic Cancer Detection on Quantum Hardware
Nandika Goyal, Glen Uehara, Andreas Spanias·Jun 19, 2026
Histopathologic cancer detection is challenging due to tissue variability, staining differences, and subtle visual distinctions between disease classes. We propose two quantum algorithms for this task: a configurable dual-gradient CSWAP circuit (DG-C...

Anderson Melchor Hernandez·Jun 19, 2026
In this work, we study the fluctuations of a Mixture of Experts (MoE) generated by a quantum neural network trained via gradient flow on supervised learning problems. Our main results establish the Central Limit Theorem (CLT), and Sanov's principle f...
