Researchers have demonstrated theoretical separations between quantum circuits and classical large language models (LLMs). The study proves that certain quantum computations, specifically those using constant-depth quantum circuits (QNC^0), can sample distributions that constant-round diffusion language models (DLMs) cannot, even with advanced techniques like chain-of-thought. Additionally, a function computable by shallow quantum circuits (O(log log n) depth) requires a significantly larger classical transformer model (width n^Ω(1)) to compute. AI
