How to Calculate the Distance in a Quantum Way?

Quantum algorithms can be used to calculate distance in this quantum way. Can you persist the quantum state from iteration to iteration, or is it kind of a start and stop the quantum process at each iteration? Exactly. So it's full quantum, i said before, but not in between iteration. And let's say that in general, being able to compute the distance and being able to access the metric or for data space, is extremey useful in so many applications. I'm glad you brought up galgan mixture model. It sounds very similar to cumens, right? Galgian mixture model is camens, but probablistic, essentially. Quantum is classical, but probabilistic,
