Somewhat off-topic, but is there a good summary of different approaches to quantum computing, and even implementation methods for each approach? I know there's at least 3-4 broad types, and I suspect each can be implemented a few different ways. Ex: there are at least a couple systems that (probably) display the topological properties needed for TQC. It's just hard to keep up with what all is out there.
