Anyone interested in learning quantum mechanics should first learn/review their linear algebra. Understanding quantum states and quantum measurements is really not that complicated once you're comfortable with vectors and matrices.

Shameless plug: I wrote a linear algebra book that discusses applications to quantum mechanics, including quantum computing.
