更重要的是,它们有助于测定量子理论和我们日常感知的边界。
Most grandly, they might help test the bounds of quantum theory and our sense of reality.
不过现如今的许多计算机科学研究更加关注时间效率,特别是NP完全问题中的理论时间边界(比如旅行商人问题,这是完全NP中一个重要的问题,译者注)。
Most of the research in Computer Science these days is devoted to time efficiency, particularly the theoretical time barrier of NP-Complete problems (like the Traveling Salesman problem).
