I'd recommend starting with Quantum Computation and Quantum Information by Isaac Chuang and Michael Nielsen ("Mike and Ike"). It's the text used in most intro courses.

There's an "Intro to Quantum Mechanics" section that covers what's strictly necessary to understand quantum algorithms.

For lectures, John Preskill's lectures from the Quantum Computation course at CalTech: https://youtube.com/playlist?list=PL0ojjrEqIyPy-1RRD8cTD_lF1...

You also need some foundation in Linear Algebra if you want to have better formal understanding of its underlying framework( which is Hilbert Space).
