LLM-Assisted Optimization for Simulation-Based Redesign
Chan-Eui Song, Jeremy J. Michalek, Christopher McComb
Engineering design frequently involves redesigning a prior solution to adapt to changes in context, such as material prices or system requirements. Redesign often leverages simulat…
Quantum Precoded Polar Codes
Tyler Kann, Shrinivas Kudekar, Matthieu R. Bloch
We introduce a new family of CSS codes obtained from rate-1 precoded polar codes, which harnesses the precoding benefits obtained for classical short blocklength polar codes. We op…
Covert Multi-bit LLM Watermarking: An Information Theory and Coding Approach
Sidong Guo, Tyler Kann, Teodora Baluta +1
We study the problem of multi-bit watermarking for non-autoregressive large language models (LLMs). We introduce an information-theoretic model inspired by diffusion language model…
Stabilizer-Code Channel Transforms Beyond Repetition Codes for Improved Hashing Bounds
Tyler Kann, Matthieu R. Bloch, Shrinivas Kudekar +1
The quantum hashing bound guarantees that rates up to are achievable for memoryless Pauli channels, but it is not generally tight. A known way to improve…
Covert Communication over Physically-Degraded Alarm Two-Way Channels
Tuna Erdoğan, Tyler Kann, Aria Nosratinia +1
We study covert communications over binary-input discrete memoryless alarm two-way channels, in which two users interact through a two-way channel and attempt to hide the presence…
