LCG: Long-Context Consistent Image Generation with Sparse Relational Attention
Zihao Wang, Yijia Xu, Haoze Zheng +3
Recent image generation models achieve impressive quality in single-image synthesis, but often fail to maintain consistency across sequential outputs, as required in comics, storyb…
Hierarchical Concept-to-Appearance Guidance for Multi-Subject Image Generation
Yijia Xu, Zihao Wang, Haokun Gui +1
Multi-subject image generation aims to synthesize images that faithfully preserve the identities of multiple reference subjects while following textual instructions. However, exist…
MalSkillBench: A Runtime-Verified Benchmark of Malicious Agent Skills
Wenbo Guo, Wei Zeng, Chengwei Liu +5
AI coding agents such as Claude Code and Gemini CLI increasingly extend themselves with third-party skills: markdown packages bundling natural-language instructions, executable scr…
Approximate quantum error correction theory of non-isometric codes
Yixu Wang, Yijia Xu, Zi-Wen Liu
Non-isometric encoding arises in various important contexts in quantum error correction, most notably in the finite-energy, non-ideal codewords inevitable in experimental realizati…
Bosonic Cyclic Codes: Trading Stabilizers for Gaussian Non-Clifford Phase Gates
Owen C. Wetherbee, Yijia Xu, Victor V. Albert +2
Bosonic codes offer hardware-efficient approaches to quantum error correction, with the best encodings offering effective protection of idle quantum information against loss and de…
A framework for low-overhead quantum fault tolerance via spacetime lifting
Yijia Xu, Yixu Wang, Zi-Wen Liu
Fault-tolerant quantum computation is inherently a spacetime problem, requiring not merely good static quantum error-correcting codes but also low-overhead protocols for protecting…
