Singleton-Optimal Rank-Metric CSS Codes : Equality Structure and Exact Projected-Recovery Radii
Myeongjun Kim, Suseong Lee, Jaeho Jeon +1
Correlated faults from shared control can have dense physical support yet low rank over a base field, motivating rank-metric quantum codes for stacked architectures. We prove an as…
Compression Asymmetry and Trajectory Binding in Noise-Anchored Diffusion Inversion
Yongseong Park, Joeun Kim, HoEun Kim +1
Real-image diffusion inversion is governed by a tight quality-cost trade-off, with costs incurred in computation, storage, or per-image optimization. We study this trade-off throug…
CORE-BREW: LLR-Based Soft Decoding for Robust Multi-Bit LLM Watermarking
Joeun Kim, HoEun Kim, Young-Sik Kim
Reliable provenance for LLM outputs requires multi-bit watermarks that remain robust under editing while maintaining low false-positive rates. Existing ECC-based LLM watermarks rel…
Block-wise Codeword Embedding for Reliable Multi-bit Text Watermarking
Joeun Kim, HoEun Kim, Dongsup Jin +1
Recent multi-bit watermarking methods for large language models (LLMs) prioritize capacity over reliability, often conflating decoding with detection. Our analysis reveals that exi…
