Artificial Entanglement in the Fine-Tuning of Large Language Models
Min Chen, Zihan Wang, Canyu Chen +3 more·Jan 11, 2026
Large language models (LLMs) can be adapted to new tasks using parameter-efficient fine-tuning (PEFT) methods that modify only a small number of trainable parameters, often through low-rank updates. In this work, we adopt a quantum-information-inspir...
Geometric and Operational Characterization of Two-Qutrit Entanglement
Ankita Jana·Jan 11, 2026
We investigate the entanglement structure of bipartite two-qutrit pure states from both geometric and operational perspectives.Using the eigenvalues of the reduced density matrix, we analyze how symmetric polynomials characterize pairwise and genuine...
Experimental Coherent One-Way Quantum Key Distribution with Simplicity and Practical Security
Xiao-Yu Cao, Xiao-Ran Sun, Ming-Yang Li +3 more·Jan 11, 2026
Coherent one-way quantum key distribution (COW-QKD) has been widely investigated, and even been deployed in real-world quantum network. However, the proposal of the zero-error attack has critically undermined its security guarantees, and existing exp...
Quantum science with arrays of metastable helium-3 atoms
Zheyuan Li, Rupsa De, Rishi Sivakumar +7 more·Jan 11, 2026
The motion of atoms in programmable optical tweezer arrays offers many new opportunities for neutral atom quantum science. These include inter- and intra-site atom motion for resource-efficient implementations of fermionic and bosonic modes, respecti...
Noise-Resistant Feature-Aware Attack Detection Using Quantum Machine Learning
Chao Ding, Shi Wang, Jingtao Sun +3 more·Jan 11, 2026
Continuous-variable quantum key distribution (CV-QKD) is a quantum communication technology that offers an unconditional security guarantee. However, the practical deployment of CV-QKD systems remains vulnerable to various quantum attacks. In this pa...
A paradigm for universal quantum information processing with integrated acousto-optic frequency beamsplitters
Joseph M. Lukens, John H. Dallyn, Hsuan-Hao Lu +5 more·Jan 11, 2026
Frequency-bin encoding offers tremendous potential in quantum photonic information processing, in which a single waveguide can support hundreds of lightpaths in a naturally phase-stable fashion. This stability, however, comes at a cost: arbitrary uni...
Non-Abelian qLDPC: TQFT Formalism, Addressable Gauging Measurement and Application to Magic State Fountain on 2D Product Codes
Guanyu Zhu, Ryohei Kobayashi, Po-Shen Hsin·Jan 11, 2026
A fundamental problem of fault-tolerant quantum computation with quantum low-density parity-check (qLDPC) codes is the tradeoff between connectivity and universality. It is widely believed that in order to perform native logical non-Clifford gates, o...
Quantum Computing and Visualization Research Challenges and Opportunities
E. Wes Bethel, Roel Van Beeumen, Talita Perciano·Jan 11, 2026
Quantum computing (QC) has experienced rapid growth in recent years with the advent of robust programming environments, readily accessible software simulators and cloud-based QC hardware platforms, and growing interest in learning how to design usefu...
Resource-Aware Task Allocator Design: Insights and Recommendations for Distributed Satellite Constellations
Bharadwaj Veeravalli·Jan 10, 2026
We present the design of a Resource-Aware Task Allocator (RATA) and an empirical analysis in handling real-time tasks for processing on Distributed Satellite Systems (DSS). We consider task processing performance across low Earth orbit (LEO) to Low-M...
Rydberg atom parity gate based on dark state resonances
Sinchan Snigdha Rej, Snigdhadev Ray, Bimalendu Deb·Jan 10, 2026
Quantum computation (QC) and digital quantum simulation (DQS) essentially require two- or multi-qubit controlled-NOT or -phase gates. We propose an alternative pathway for QC and DQS using a three-qubit parity gate in a Rydberg atom array. The basic ...
Chip-integrated metasurface-enabled single-photon skyrmion sources
Xujing Liu, Yinhui Kan, Shailesh Kumar +4 more·Jan 10, 2026
Skyrmions, topologically stable field configurations, have recently emerged in classical optics as structured light for high-density data applications. Achieving controllable on-chip generation of single-photon skyrmions, while being highly desirable...
Kara-Kichwa Data Sovereignty Framework: Reference Point for Indigenous Data Authority Renaissances in LAC
WariNkwi K. Flores, KunTikzi Flores, Rosa M. Panama +1 more·Jan 10, 2026
For Indigenous Peoples of the Apya Yala (or Abya Yala), particularly in the Kara and Kichwa citizens of the Pan-Andean-Amazonian biocultural region, data is not merely a knowledge or information resource, it is the extension of Khipu Panaka (Indigeno...
Wave Function Realism and the Mathematization of Nature. A Phenomenological Perspective
Philipp Berghofer, Harald A. Wiltsche·Jan 10, 2026
This chapter reexamines wave function realism (WFR) through the lens of phenomenology. We begin by situating WFR within the broader debate about the ontology of the quantum state and the temptation to "read off" metaphysics from mathematical formalis...
Magnetic levitation and spatial superposition of a nanodiamond with a current-carrying chip
Qian Xiang, Shafaq Gulzar Elahi, Andrew Geraci +2 more·Jan 10, 2026
We propose a current-carrying-chip scheme for generating spatial quantum superpositions using a levitating nanodiamond with a built-in nitrogen-vacancy (NV) centre defect. Our setup is quite versatile and we aim to create the superposition for a mass...
Transfer of Orbital Angular Momentum in Vortex Light through Four-Wave Mixing and the Manipulation of Slow and Fast Light
Fan Meng, Xin-Yao Huang, Guo-Feng Zhang·Jan 10, 2026
Vortex light, a unique optical field that carries orbital angular momentum (OAM), has attracted considerable attention in recent years. In this paper, we present a detailed theoretical analysis of OAM transfer from the input field to the generated si...
Spontaneous Brillouin Scattering in a Few-Mode Optical Fiber
Hikari Kikuchi, Rekishu Yamazaki·Jan 10, 2026
We report a comprehensive experimental study of spontaneous Brillouin scattering in a few-mode optical fiber, resolving both forward and backward scattering processes for intra- and inter-modal interactions. Using heterodyne detection, Stokes and ant...
Digital Predistortion of Power Amplifiers for Quantum Computing
Marvin Jaeger, Bartosz Tegowski, Georg Frederik Riemschneider +1 more·Jan 10, 2026
Power amplifiers (PA) are essential for microwavecontrolled trapped-ion and semiconductor spin based quantum computers (QC). They adjust the power level of the control signal and therefore the processing time of the QC. Their nonlinearities and memor...
Restoring Locality: The Heisenberg Picture as a Separable Description of Quantum Theory
Sam Kuypers·Jan 10, 2026
Local realism has been the subject of much discussion in modern physics, partly because our deepest theories of physics appear to contradict one another in regard to whether reality is local. According to general relativity, it is, as physical quanti...
