I’d like to really flesh out that page; I’ve now come across so many folks that are amazing at explaining this stuff... It’s just a time crunch to juggle all this as you might imagine ;)
These two videos in particular helped me get started:
It simulates a simple model of a quantum computer, so that you can implement and test out quantum algorithms, albeit at potentially huge computational cost.
quantum.country is a good introduction to quantum computing for people with no background other than linear algebra. Even if you don't understand linear algebra you could probably skim it and get a sense for what's going on.
