I remember looking up stuff on quantum computing a few years back. At the time a lot of the YouTube videos were by maths professors, and they were all very good and didn't skip on the complex maths (although I got the gist, a lot went over my head, but I knew I could probably get it if I reviewed all my polar/complex notation and maths). Some videos used some of the simulators that could simulate a few qbits. I remember that as you added qbits, the amount of ram you needed grew massively (exponentially?). Everything that could be done with a quantum machine could be done with a classical machine, it would just have larger space or time requirements. I feel like this comic tries to get across a lot of the higher level concepts without using the stupid analogies used in a lot of pop science articles. It's not necessary for understanding the actual maths, but it does help with larger concepts. It's honestly something I'd expect from PhD comics. I stopped reading both SMBC and PhD a while back; need to catch up on my RSS feeds :)
