XBTorch: A Unified Framework for Modeling and Co-Design of Crossbar-Based Deep Learning Accelerators
Osama Yousuf, Andreu L. Glasmann, Martin Lueker-Boden +2 more·Jan 11, 2026
Emerging memory technologies have gained significant attention as a promising pathway to overcome the limitations of conventional computing architectures in deep learning applications. By enabling computation directly within memory, these technologie...
Nonadiabatic theory for subcycle ionic dynamics in multielectron tunneling ionization
Chi-Hong Yuen·Jan 11, 2026
Multielectron tunneling ionization creates ionic coherence crucial for lasing and driving electron motion in molecules. While tunneling is well understood as a single active electron process, less emphasis has been placed on theoretical descriptions ...
Stochastic phase-space simulation of multimode cat states via the positive-P representation
Yi Shi, Alex Ferrier, Piotr Deuar +2 more·Jan 11, 2026
We present a comprehensive study of the transient dynamics of multimode Schrödinger cat states in dissipatively coupled resonator arrays using the positive-P phase-space method. By employing the positive-P representation, we derive the exact stochast...
Subspace Selected Variational Quantum Configuration Interaction with a Partial Walsh Series
Koray Aydoğan, Anna R. Spak, Kade Head-Marsden +1 more·Jan 11, 2026
Estimating the ground-state energy of a quantum system is one of the most promising applications for quantum algorithms. Here we propose a variational quantum eigensolver (VQE) \emph{Ansatz} for finding ground state configuration interaction (CI) wav...
Irreversibility of decorrelating processes: an experimental assessment in cavity QED
Guillaume Cœuret Cauquil, Patrice A. Camati, Irénée Frerot +3 more·Jan 11, 2026
Entropy production quantifies the amount of irreversibility of a physical process, leading to fundamental bounds for thermodynamic quantities. Particularly in the quantum realm, considerable research has been carried out in the last decades extending...
Graphene-assisted resonant transmission and enhanced Goos-Hänchen shift in a frustrated total internal reflection configuration
Yi Chen, Yue Ban, Qi-Biao Zhu +1 more·Jan 11, 2026
Graphene-assisted resonant transmission and enhanced Goos-Hänchen shift are investigated in a two-prism frustrated-total-internal-reflection configuration. Due to the excitation of surface plasmons induced by graphene in low terahertz frequency range...
Quantum state engineering of spin-orbit coupled ultracold atoms in a Morse potential
Yue Ban, Xi Chen, J. G. Muga +1 more·Jan 11, 2026
Achieving full control of a Bose-Einstein condensate can have valuable applications in metrology, quantum information processing, and quantum condensed matter physics. We propose protocols to simultaneously control the internal (related to its pseudo...
Counter-diabatic driving for fast spin control in a two-electron double quantum dot
Yue Ban, Xi Chen·Jan 11, 2026
The techniques of shortcuts to adiabaticity have been proposed to accelerate the "slow" adiabatic processes in various quantum systems with the applications in quantum information processing. In this paper, we study the counter-diabatic driving for f...
Dynamical Correlation of the Post-quench Non-thermal Equilibrium State
Yang-Yang Chen, Song Cheng·Jan 11, 2026
After a quantum quench, the integrable system is expected to relax to a non-thermal equilibrium state (NTES) whose local properties are believed to be governed by a generalized Gibbs ensemble (GGE). Combining quench action and the form factor approac...
Essentially No Energy Barrier Between Independent Fermionic Neural Quantum State Minima
David D. Dai, Marin Soljačić·Jan 11, 2026
Neural quantum states (NQS) have proven highly effective in representing quantum many-body wavefunctions, but their loss landscape remains poorly understood and debated. Here, we demonstrate that the NQS loss landscape is more benign and similar to c...
Extending the Handover-Iterative VQE to Challenging Strongly Correlated Systems: $N_2$ and Fe-S Cluster
Pilsun Yoo, Kyungmin Kim, Eyuel E. Elala +10 more·Jan 11, 2026
Accurately describing strongly correlated electronic systems remains a central challenge in quantum chemistry, as electron-electron interactions give rise to complex many-body wavefunctions that are difficult to capture with conventional approximatio...
High-capacity dual degrees of freedom quantum secret sharing protocol beyond the linear rate-distance bound
Meng-Dong Zhu, Cheng Zhang, Shi-Pu Gu +5 more·Jan 11, 2026
Quantum secret sharing (QSS) is the multipartite cryptographic primitive. Most of existing QSS protocols are limited by the linear rate-distance bound, and cannot realize the long-distance and high-capacity multipartite key distribution. This paper p...
Resilience by Design: A KPI for Heavy-Duty Megawatt Charging
Sonia Yeh, Rishabh Ghotge, Yujia Shi +1 more·Jan 11, 2026
We introduce a stressor-agnostic Resilience Key Performance Indicator (Resilience KPI) for megawatt charging stations (MSC) serving heavy-duty vehicles. Beyond routine performance statistics (e.g., availability, throughput), the KPI quantifies a site...
How Do Ports Organise Innovation? Linking Port Governance, Ownership, and Living Labs
Sonia Yeh, Christopher Dirzka, Aleksandr Kondratenko +2 more·Jan 11, 2026
Ports are pivotal to decarbonisation and resilience, yet port studies rarely examine how ownership and decision rights shape the process and outcomes of sustainability and digital pilots. Living Lab (LL) scholarship offers strong concepts, but limite...
Understanding the Performance Behaviors of End-to-End Protein Design Pipelines on GPUs
Jinwoo Hwang, Yeongmin Hwang, Tadiwos Meaza +2 more·Jan 11, 2026
Recent computational advances enable protein design pipelines to run end-to-end on GPUs, yet their heterogeneous computational behaviors remain undercharacterized at the system level. We implement and profile a representative pipeline at both compone...
Coherent Control of the Goos-Hänchen Shift in Polariton Optomechanics
Shah Fahad, Gao Xianlong·Jan 11, 2026
We propose a theoretical scheme for controlling the Goos-Hänchen shift (GHS) of a reflected probe field in a polariton optomechanical system. The system comprises an optical mode, a molecular vibrational mode, and $N$ excitonic modes, where excitons ...
