The concept of types of quantum states is genuinely new to me, and finding this awakens that joy of discovery in me. I've seen enough about quantum theory and quantum computing to conclude there is definitely something real there. But work in the field - such as this paper, also on quantum states - is beyond what I can understand without a lot of focused study. Ah, maybe, one day. The key thing to undertsand here is that it's not nonsense - it's real (so far as anything counts as 'real' in the quantum world). I did some quick reading today aftern seeing this diagram in a post by Sumit Patel in LinkedIn. I didn't think it would be definitive (after all, this is LinkedIn we're talking about). The article I link to here as several other diagrams of types of quantum states. It just underlines the fact that 'types' are things that we as viewers bring to the world; they're not inherently in the world, not until they're recognized as such.
