Evaluating QAOA expectation values can be as hard as counting optimal solutions

Stuart Hadfield

Evaluating expectation values is a critical task for variational quantum eigensolvers, and for parameterized quantum circuits and other quantum algorithms more generally. We consid…

SCOPE: Leveraging Subgoal Critiques for Code Generation

Yueke Zhang, Yifan Zhang, Zihan Fang +3

Code generation with large language models (LLMs) remains unreliable because generated programs can appear correct while still violating key semantic requirements in the natural la…

DPO-F+: Aligning Code Repair Feedback with Developers' Preferences

Zihan Fang, Yifan Zhang, Yueke Zhang +2

Large Language Models (LLMs) are increasingly used in software engineering tasks, especially code repair. However, developers often struggle to interpret model outputs, limiting ef…

SynthFix: Adaptive Neuro-Symbolic Code Vulnerability Repair

Yifan Zhang, Jieyu Li, Kexin Pei +2

Large Language Models (LLMs) can generate plausible code patches, but plausibility is not enough for automated repair: a patch must compile, pass tests, and remove the target vulne…

EyeMulator: Improving Code Language Models by Mimicking Human Visual Attention

Yifan Zhang, Chen Huang, Yueke Zhang +5

Code Language Models (CodeLLMs) learn token importance from data correlations, whereas human developers attend selectively to semantically salient code. We present EyeMulator, a mo…

VERITAS: Verifier-Guided Proof Search for Zero-Shot Formal Theorem Proving

Manish Acharya, Zhenyu Liao, Yueke Zhang +3

LLM-based formal provers often collapse rich verifier signals (syntax errors, type mismatches, partial goal progress) into a binary pass/fail bit. We present VERITAS, a zero-shot f…
