Pump Free Microwave-Optical Quantum Transduction
Fangxin Li, Jaesung Heo, Zhaoyou Wang +3 more·Dec 4, 2025
Distributed quantum computing involves superconducting computation nodes operating at microwave frequencies, which are connected by long-distance transmission lines that transmit photons at optical frequencies. Quantum transduction, which coherently ...
Multimode RF Reflectometry for Spin Qubit Readout and Device Characterization
Joffrey Rivard, Alexis Morel, Olivier Romain +10 more·Dec 4, 2025
We introduce a multimode superconducting inductor architecture that enables radio-frequency reflectometry at multiple discrete frequencies up to 2 GHz, addressing limitations of conventional single-mode designs. The spiral inductor's distributed inte...
Deadline-Aware Scheduling of Distributed Quantum Circuits in Near-Term Quantum Cloud
Nour Dehaini, Christia Chahoud, Mahdi Chehimi·Dec 4, 2025
Distributed quantum computing (DQC) enables scalable quantum computations by distributing large quantum circuits on multiple quantum processing units (QPUs) in the quantum cloud. In DQC, after partitioning quantum circuits, they must be scheduled and...
Thermodynamic universality across dissipative quantum phase transitions
Laetitia P. Bettmann, Artur M. Lacerda, Mark T. Mitchison +1 more·Dec 4, 2025
We study finite-time driving across second-order dissipative quantum phase transitions described by Lindblad dynamics. We show that the nonadiabatic entropy production, which quantifies deviations from the instantaneous nonequilibrium steady state, e...
Hybrid Quantum-Classical Autoencoders for Unsupervised Network Intrusion Detection
Mohammad Arif Rasyidi, Omar Alhussein, Sami Muhaidat +1 more·Dec 4, 2025
Unsupervised anomaly-based intrusion detection requires models that can generalize to attack patterns not observed during training. This work presents the first large-scale evaluation of hybrid quantum-classical (HQC) autoencoders for this task. We c...
Meta-Learning for Quantum Optimization via Quantum Sequence Model
Yu-Cheng Lin, Yu-Chao Hsu, Samuel Yen-Chi Chen·Dec 4, 2025
The Quantum Approximate Optimization Algorithm (QAOA) is a leading approach for solving combinatorial optimization problems on near-term quantum processors. However, finding good variational parameters remains a significant challenge due to the non-c...
High Fidelity Qubit Control in a Natural Si-MOS Quantum Dot using a 300 mm Silicon on Insulator Wafer
Xander Peetroons, Xunyao Luo, Tsung-Yeh Yang +26 more·Dec 4, 2025
We demonstrate high-fidelity single qubit control in a natural Si-MOS quantum dot fabricated in an industrial 300 mm wafer process on a silicon on insulator (SOI) wafer using electron spin resonance. A relatively high optimal Rabi frequency of 5 MHz ...
QKAN-LSTM: Quantum-inspired Kolmogorov-Arnold Long Short-term Memory
Yu-Chao Hsu, Jiun-Cheng Jiang, Chun-Hua Lin +5 more·Dec 4, 2025
Long short-term memory (LSTM) models are a particular type of recurrent neural networks (RNNs) that are central to sequential modeling tasks in domains such as urban telecommunication forecasting, where temporal correlations and nonlinear dependencie...
Expanding the Neutral Atom Gate Set: Native iSWAP and Exchange Gates from Dipolar Rydberg Interactions
Pedro Ildefonso, Andrew Byun, Aleksei Konovalov +3 more·Dec 4, 2025
We present a native realization of iSWAP and parameterized exchange gates for neutral atom quantum processing units. Our approach leverages strong dipole-dipole interactions between two dipole-coupled Rydberg states, and employs optimal control techn...
Tractatus Quanticum
Niccolò Covoni, Carlo Rovelli·Dec 4, 2025
This is a re-editing, which takes quantum mechanics into account, of Wittgenstein's famous Tractatus. The operation has a playful side in the form, but is a serious attempt to capture possible philosophical implications of the Relational Interpretati...
Emergence of ER=EPR from non-local gravitational energy
Kimet Jusufi, Francisco S. N. Lobo, Emmanuel N. Saridakis +1 more·Dec 4, 2025
We construct a class of wormhole geometries supported by the non-local gravitational self-energy that regularizes the particle and black-hole sectors of spacetime. Using this framework, inspired by T-duality, we show that two entangled particles (or ...
The Magnus expansion in relativistic quantum field theory
Andreas Brandhuber, Graham R. Brown, Paolo Pichini +2 more·Dec 4, 2025
We investigate the Magnus expansion of the $N$-operator in relativistic quantum field theory, which is related to the $S$-matrix via $S = e^{iN}$. We develop direct methods to compute matrix elements of the $N$-operator, which we refer to as Magnus a...
Transverse response from anisotropic Fermi surfaces
Abhiram Soori·Dec 4, 2025
We demonstrate that an anisotropic and rotated Fermi surface can generate a finite transverse response in electron transport, even in the absence of a magnetic field or Berry curvature. Using a two-dimensional continuum model, we show that broken $k_...
Quantum open system description of a hybrid plasmonic cavity
Marco Vallone·Dec 4, 2025
We present a unified quantum open system framework for lossy plasmonic cavities in which coherent dynamics, relaxation, dephasing, and irreversible absorption are treated on equal footing. The Dyson equation for the cavity photon propagator in the ra...
Introduction to quantum control: From basic concepts to applications in quantum technologies
Christiane P. Koch·Dec 4, 2025
Quantum control refers to our ability to manipulate quantum systems. This tutorial-style chapter focuses on the use of classical electromagnetic fields to steer the system dynamics. In this approach, the quantum nature of the control stems solely fro...
