Does anyone know a good resource about quantum computing for quantum physics beginners? I've tried to understand the concepts from Wikipedia, but it's a bit too abstract and I keep on getting lost down the rabbit hole reading up about the QP terms being used.

All I understand so far is that apparently, thanks to many independently controllable quantum states, some NP problems can be solved in polynomial time. If I'm not mistaken, this would require infinitely many possible different quantum states, but I've never seen this stated (or contradicted) explicitly anywhere.
