 And so that's a time, it's a spatial kind of time-related phenomena. So it's not surprising that people are starting to realize that time is an important characteristic of quantum computing. It's the same thing that's related to Shor's algorithm. Shor's algorithm shows that you can solve a problem that no classical computer can solve, no classical algorithm can solve. And so it's sort of like, how can we all of a sudden speed up an algorithm, which is a temporal idea,
