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.

Thanks for posting this.

A note: Several of the links you posted aren't valid. "Measuring a qubit", "Why unitaries are the only matrices which preserve length", "Superdense coding: how to send two bits using one qubit", "Preparing the Bell state"

There's something weird going on with the links, but I'm starting to think the problem may be Firefox's, not yours. Sometimes they point correctly, sometimes they link back to this page.

This is excellent. Thank you for beginning with the basics.

One confusion. I'm only three videos in and you have suggested the mediums that could carry quantum information, but not how that information is produced in those mediums, read from those mediums, or stored.

That's what a superposition is! Finally!

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.

Many, many many thanks! I will delve and post questions if you agree
