FVQKD: A Formal Verification of Quantum Key Distribution Security in Rocq

Ruixuan Deng, Zhengfeng Ji, Jiayu Zhang +1

Quantum key distribution (QKD), whose security is derived from quantum mechanics rather than computational assumptions, is moving into standardization and commercial deployment. Ye…

Transformers Stop Thinking Too Early, and a Tiny LoRA Fixes It

Zehao Jin, Ruixuan Deng, Junran Wang

Pretrained transformers use little of their depth to follow references in context. Thirteen base models reliably follow only 1.4-3.6 lines, and extra pretrained loops add little. A…

Persona Dosing: Calibrated Activation Steering for Graded Trait Control

Zehao Jin, Junran Wang, Ruixuan Deng +4

An activation-steering coefficient sets intervention strength, but requesting a particular degree of persona expression requires a behavioral scale. We study persona dosing: contro…

Long-horizon autoformalization of a core theorem underlying MIP* = RE

Sirui Lu, Ruixuan Deng, David Zhu +2

Landmark mathematical formalizations have taken specialist teams years to complete. We present FormalFlow, a system that coordinates AI proving agents under human supervision to ad…

How Benchmarks Mis-Score Computer-Use Agents

Zihan Dong, Zhiyuan Ma, Zekun Wang +5

Computer-use agents (CUA) are being deployed to browse the web and operate desktop software, yet their benchmark scores are still commonly produced by brittle scripted oracles. A s…

Decompose Sparsely Where You Should, Absorb Densely Where You Should No

Ruixuan Deng, Zehao Jin, Zekun Wang +1

Sparse autoencoders (SAEs) are typically trained to reconstruct the \textbf{entire} residual stream through a sparse dictionary, implicitly assuming that all activation content is…

Beyond Steering Vector: Flow-based Activation Steering for Inference-Time Intervention

Zehao Jin, Ruixuan Deng, Junran Wang +2

Activation steering has emerged as a promising alternative for controlling language-model behavior at inference time by modifying intermediate representations while keeping model p…

Breaking the Treewidth Barrier in Quantum Circuit Simulation with Decision Diagrams

Bin Cheng, Ziyuan Wang, Ruixuan Deng +2

Classical simulation of quantum circuits is a critical tool for validating quantum hardware and probing the boundary between classical and quantum computational power. Existing sta…

Sparse Feature Coactivation Reveals Causal Semantic Modules in Large Language Models

Ruixuan Deng, Xiaoyang Hu, Miles Gilberti +5

We identify semantically coherent, context-consistent network components in large language models (LLMs) using coactivation of sparse autoencoder (SAE) features collected from just…

Control Flow Adaption: An Efficient Simulation Method For Noisy Quantum Networks

Huiping Lin, Ruixuan Deng, Chris Z. Yao +2

Quantum network research at both the software stack and hardware implementation level has become an exciting area of quantum information science. Although demonstrations of small-s…

Koopman neural operator as a mesh-free solver of non-linear partial differential equations

Wei Xiong, Xiaomeng Huang, Ziyang Zhang +3

The lacking of analytic solutions of diverse partial differential equations (PDEs) gives birth to a series of computational techniques for numerical solutions. Although numerous la…
