Quantum-Inspired Attention Mechanism Offers Memory Efficiency in Language Models

Researchers have developed Q-Interference, a novel classical attention mechanism inspired by quantum principles for autoregressive language models. This method enhances standard GPT attention by incorporating phase-aware interactions, allowing aligned features to reinforce and conflicting ones to cancel out. To overcome the memory-intensive nature of this approach, an exact trigonometric factorization is employed, enabling efficient computation through standard matrix multiplications without needing a large intermediate tensor. Experiments indicate that Q-Interference trains stably and offers a memory advantage over existing phase-aware attention methods within a typical GPT pipeline. AI
