Thanks. I like the description from the wiki.

According to the Copenhagen interpretation, physical systems generally do not have definite properties prior to being measured, and quantum mechanics can only predict the probabilities that measurements will produce certain results.

There are some similarities of what you said but not exactly the same. I don’t like the Schrödinger’s cat thought experiment because it can create more questions than answers. Actually, I just change the article and not to mention it after reading your comment.

So does state cease to matter? In a certain way, yes. But, we do a lot of math to model how superposition states evolve, so I will not reach too far either. Without that, there is no quantum computing.

My thought is if you really need to ask what happen, you can hypothesize it. But it is unlikely the scope of quantum mechanics will give you the answer. So the superposition concept is a convenient way to move forward to develop the math model and the superposition is an easy way to explain things even what behind the scene may lead to many curious questions.

Thanks for your comment.
