21 videos, which cover subjects including the basic model of quantum computing, entanglement, superdense coding, and quantum teleportation.
To work through the videos you need to be comfortable with basic linear algebra, and with assimilating new mathematical terminology. If you’re not, working through the videos will be arduous at best! Apart from that background, the main prerequisite is determination, and the willingness to work more than once over material you don’t fully understand.
In particular, you don’t need a background in quantum mechanics to follow the videos.
The videos are short, from 5-15 minutes, and each video focuses on explaining one main concept from quantum mechanics or quantum computing. In taking this approach I was inspired by the excellent Khan Academy.
It's been driving me up the wall that most descriptions of quantum computing really consist of 8-9 loosely related paragraphs followed by a reference to computational speed and super encryption.
