Question: I was wandering, you mentioned this material to be in two states (0 and 1 simultaneously) but are there materials which can be in more than two states? If it would be possible, we could have a decimal computer!

  That’s a good point – you can take an electron and put into a superposition of 3 distinct states (‘superposition’ is how we say it’s in more than one state). It turns out however that doing this is really hard, and is not actually so much more useful than just having a superposition over 2 states. Good point though. It’s good to know you’ve understood the idea of it!
