The Dynamics of Attention across Automated and Manual Driving Modes: A Driving Simulation Study
Yuan Cai, Mustafa Demir, Farzan Sasangohar +1 more·Feb 4, 2026
This study aims to explore the dynamics of driver attention to various zones, including the road, the central mirror, the embedded Human-Machine Interface (HMI), and the speedometer, across different driving modes in AVs. The integration of autonomou...
A computational account of dreaming: learning and memory consolidation
Qi Zhang·Feb 4, 2026
A number of studies have concluded that dreaming is mostly caused by randomly arriving internal signals because "dream contents are random impulses", and argued that dream sleep is unlikely to play an important part in our intellectual capacity. On t...
Approximate simulation of complex quantum circuits using sparse tensors
Benjamin N. Miller, Peter K. Elgee, Jason R. Pruitt +1 more·Feb 3, 2026
The study of quantum circuit simulation using classical computers is a key research topic that helps define the boundary of verifiable quantum advantage, solve quantum many-body problems, and inform development of quantum hardware and software. Tenso...
Universal Characterization of Quantum Vacuum Measurement Engines
Robert Czupryniak, Bibek Bhandari, Paolo Andrea Erdman +1 more·Feb 3, 2026
Quantum measurements can inject energy into quantum systems, enabling engines whose operation is powered entirely by measurements. We develop a general theory of quantum vacuum measurement engines by introducing the quantum vacuum bending function (Q...
Optimal Effective Hamiltonian for Quantum Computing and Simulation
Hao-Yu Guan, Xiao-Long Zhu, Yu-Hang Dang +1 more·Feb 3, 2026
The effective Hamiltonian serves as the conceptual pivot of quantum engineering, transforming physical complexity into programmable logic; yet, its construction remains compromised by the mathematical non-uniqueness of block diagonalization, which in...
An Evaluation of the Remote CX Protocol under Noise in Distributed Quantum Computing
Leo Sünkel, Michael Kölle, Tobias Rohe +1 more·Feb 3, 2026
Quantum computers connected through classical and quantum communication channels can be combined to function as a single unit to run large quantum circuits that each device is unable to execute on their own. The distributed quantum computing paradigm...
Evaluating Quantum Wire Cutting for QAOA: Performance Benchmarks in Ideal and Noisy Environments
Michel Meulen, Niels M. P. Neumann, Jasper Verbree·Feb 3, 2026
Current quantum computers suffer from a limited number of qubits and high error rates, limiting practical applicability. Different techniques exist to mitigate these effects and run larger algorithms. In this work, we analyze one of these techniques ...
Even More Efficient Soft-Output Decoding with Extra-Cluster Growth and Early Stopping
Kaito Kishi, Riki Toshio, Jun Fujisaki +3 more·Feb 3, 2026
In fault-tolerant quantum computing, soft outputs from real-time decoders play a crucial role in improving decoding accuracy, post-selecting magic states, and accelerating lattice surgery. A recent paper by Meister et al. [arXiv:2405.07433 (2024)] pr...
Tuning interactions between static-field-shielded polar molecules with microwaves
Christopher J. Ho, Joy Dutta, Bijit Mukherjee +2 more·Feb 3, 2026
The ability to tune interparticle interactions is one of the main advantages of using ultracold quantum gases for quantum simulation of many-body physics. Current experiments with ultracold polar molecules employ shielding with microwave or static el...
Resource-efficient quantum simulation of transport phenomena via Hamiltonian embedding
Joseph Li, Gengzhi Yang, Jiaqi Leng +1 more·Feb 3, 2026
Transport phenomena play a key role in a variety of application domains, and efficient simulation of these dynamics remains an outstanding challenge. While quantum computers offer potential for significant speedups, existing algorithms either lack ri...
Device variability of Josephson junctions induced by interface roughness
Yu Zhu, Félix Beaudoin, Hong Guo·Feb 3, 2026
As quantum processors scale to large qubit numbers, device-to-device variability emerges as a critical challenge. Superconducting qubits are commonly realized using Al/AlO$_{\text{x}}$/Al Josephson junctions operating in the tunneling regime, where e...

Karim Essalmi, Fernando Garrido, F. Nashashibi·Feb 3, 2026
Although significant progress has been made in decision-making for automated driving, challenges remain for deployment in the real world. One challenge lies in addressing interaction-awareness. Most existing approaches oversimplify interactions betwe...

Luciano Loris Viteritti, Riccardo Rende, Subir Sachdev +1 more·Feb 2, 2026
Accessing the thermodynamic-limit properties of strongly correlated quantum matter requires simulations on very large lattices, a regime that remains challenging for numerical methods, especially in frustrated two-dimensional systems. We introduce th...
