VOLMO: Versatile and Open Large Models for Ophthalmology
Zhenyue Qin, Younjoon Chung, Elijah Lee +16 more·Mar 25, 2026
Vision impairment affects millions globally, and early detection is critical to preventing irreversible vision loss. Ophthalmology workflows require clinicians to integrate medical images, structured clinical data, and free-text notes to determine di...
Thermalization of SU(2) Lattice Gauge Fields on Quantum Computers
Jiunn-Wei Chen, Yu-Ting Chen, Ghanashyam Meher +3 more·Mar 25, 2026
We simulate the thermalization dynamics for minimally truncated SU(2) pure gauge theory on linear plaquette chains with up to 151 plaquettes using IBM quantum computers. We study the time dependence of the entanglement spectrum, Rényi-2 entropy and a...
Quantum Computing and Error Mitigation with Deep Learning for Frenkel Excitons
Yi-Ting Lee, Vijaya Begum-Hudde, Barbara A. Jones +1 more·Mar 25, 2026
Quantum computers, currently in the noisy intermediate-scale quantum (NISQ) era, have started to provide scientists with a novel tool to explore quantum physics and chemistry. While several electronic systems have been extensively studied, Frenkel ex...
Energy Balance of a Boson Gas at Zero Temperature in Curved Spacetime
Jorge Meza-Domínguez, Tonatiuh Matos, Pierre-Henri Chavanis·Mar 25, 2026
We develop a comprehensive thermodynamic description for a zero-temperature boson gas in curved spacetime, integrating energy conservation with information-theoretic principles. Using the hydrodynamic Madelung representation within the ADM formalism,...
Efficient Preparation of Graph States using the Quotient-Augmented Strong Split Tree
Nicholas Connolly, Shin Nishio, Dan E. Browne +2 more·Mar 25, 2026
Graph states are a key resource for measurement-based quantum computation and quantum networking, but state-preparation costs limit their practical use. Graph states related by local complement (LC) operations are equivalent up to single-qubit Cliffo...
Predicting quantum ground-state energy by data-driven Koopman analysis of variational parameter nonlinear dynamics
Nobuyuki Okuma·Mar 25, 2026
In recent years, the application of machine learning to physics has been actively explored. In this paper, we study a method for estimating the ground-state energy of quantum Hamiltonians by applying data-driven Koopman analysis within the framework ...
Identical Quantum Particles as Potential Parts
Philip Goyal·Mar 25, 2026
The mathematical rules used to handle systems of identical quantum particles bring into question whether the elementary constituents of matter, such as electrons, have the fundamental characteristics of persistence and reidentifiability that are usua...
Precision bounds for frequency estimation under collective dephasing and open-loop control
Francisco Riberi, Gerardo Paz-Silva, Lorenza Viola·Mar 25, 2026
Dephasing noise is a ubiquitous source of decoherence in current atomic sensors. We address the problem of entanglement-assisted frequency estimation subject to classical dephasing noise with full spatial correlations (collective) and arbitrary tempo...
Quantum photonic neural networks in time
Ivanna M. Boras Vazquez, Jacob Ewaniuk, Nir Rotenberg·Mar 25, 2026
We introduce the architecture and timing algorithm to realize a time-bin-encoded quantum photonic neural network (QPNN): a reconfigurable nonlinear photonic circuit inspired by the brain and trained to process quantum information. Unlike the typical ...
Mitigating Barren Plateaus via Domain Decomposition in Variational Quantum Algorithms for Nonlinear PDEs
Laila S. Busaleh, J. Kwon, Orlane Zang +2 more·Mar 25, 2026
Barren plateaus present a major challenge in the training of variational quantum algorithms (VQAs), particularly for large-scale discretizations of nonlinear partial differential equations. In this work, we introduce a domain decomposition framework ...
Kinetics-Driven Selective Stoichiometric Shift and Structural Asymmetry in $Bi_4Te_3$ Nanostructures for Hybrid Quantum Architectures
Abdur Rehman Jalil, H. Valencia, Christoph Ringkamp +6 more·Mar 25, 2026
Advances in hybrid quantum architectures hinge on topological materials that can be synthesized with precise stoichiometric and structural control at the nanoscale. While $Bi_4Te_3$ is a promising candidate due to its dual topological phases, acting ...
The quantum harmonic oscillator on a circle -- fragmentation of the algebraic method
Daniel Burgarth, Paolo Facchi·Mar 24, 2026
A quantum particle on a circle in a quadratic potential exhibits a spectrum that is not harmonic, despite having all algebraic properties of the quantum harmonic oscillator. This raises the question where the usual algebraic argument -- implying inte...
PIM-CACHE: High-Efficiency Content-Aware Copy for Processing-In-Memory
Peterson Yuhala, Mpoki Mwaisela, Pascal Felber +1 more·Mar 24, 2026
Processing-in-memory (PIM) architectures bring computation closer to data, reducing the processor-memory transfer bottleneck in traditional processor-centric designs. Novel hardware solutions, such as UPMEM's in-memory processing technology, achieve ...
Quantum-classical dynamics of Rashba spin-orbit coupling
Paul Bergold, Giovanni Manfredi, Cesare Tronci·Mar 24, 2026
Mixed quantum-classical models are widely used to reduce the computational cost of fully quantum simulations. However, their general applicability across different classes of problems remains an open question. Here, we address this issue for systems ...
Very sensitive vapor-cell quasi-DC atomic E-field sensor
Amy Damitz, George Burns, Yuan-Yu Jau·Mar 24, 2026
We report several technical approaches that significantly improve the performance of a vapor-cell atomic electrometer operating in the quasi-DC frequency domain ($\ll$ 1 kHz). With a very small active volume of approximately 11 mm$^3$ inside the vapo...
