Space-Efficient Quantum Algorithm for Elliptic Curve Discrete Logarithms with Resource Estimation
Han Luo, Ziyi Yang, Ziruo Wang +2
Solving the Elliptic Curve Discrete Logarithm Problem (ECDLP) is critical for evaluating the quantum security of widely deployed elliptic-curve cryptosystems. Consequently, minimiz…
LWE with Quantum Amplitudes: Algorithm, Hardness, and Oblivious Sampling
Yilei Chen, Zihan Hu, Qipeng Liu +2
In this paper, we show new algorithms, hardness results and applications for and with real Gaussian, Gaussian with linear or quadratic phase…
Agentic Abstention: Do Agents Know When to Stop Instead of Act?
Han Luo, Bingbing Wen, Lucy Lu Wang
LLM agents are expected to act over multiple turns, using search, browsing interfaces, and terminal tools to complete user goals. Yet not every goal is well specified or achievable…
DialogGuard: Multi-Agent Psychosocial Safety Evaluation of Sensitive LLM Responses
Han Luo, Guy Laban
Large language models (LLMs) now mediate many web-based mental-health, crisis, and other emotionally sensitive services, yet their psychosocial safety in these settings remains poo…
Plan in Sandbox, Navigate in Open Worlds: Learning Physics-Grounded Abstracted Experience for Embodied Navigation
Zhixuan Shen, Jiawei Du, Ziyu Guo +5
Vision-Language Models (VLMs) have demonstrated exceptional general reasoning capabilities. However, their performance in embodied navigation remains hindered by a scarcity of alig…
Liouville theorem for -harmonic heat flows
Han Luo, Weike Yu, Xi Zhang
In this paper, we investigate -harmonic heat flows from complete Riemannian manifolds with nonnegative Bakry-Emery Ricci curvature to complete Riemannian manifolds with sectiona…
