Nielsen and Chuang has the clearest exposition of quantum mechanics I've seen anywhere. Last year I was trying to learn quantum mechanics, not necessarily quantum computation, just out of a general interest in theoretical physics. I started with physics textbooks (Griffiths and Shankar) but it only really "clicked" for me when I read the first few chapters of Nielsen and Chuang.

I came across A free introduction to quantum computing and quantum mechanics by Nielsen/Matuschak which seems accessible - https://quantum.country/
