The qubit

Quantum Computing for the Determined isn't a book but a series of short lectures Khan Academy style. I found it an excellent introduction to the subject of quantum computing. It's probably closer to the computer engineer's understanding of a quantum computer than computer science but it's well above the physics and material science layers.

Heres a playlist where you can actually learn about quantum computing link to this video Quantum Computing for the determined by Micheal Nielsen. Requires undergraduate understanding of linear algebra and computer science background to understand.

Quantum computing for the determined, have all your quantum computing questions answered, note that this is NOT for physicists, it goes over the ***computer science*** workings of quantum computing. Quantum computing works on systems with quantum functionality, in particular it relies on entanglement principles, which is covered in the video series below. Don't listen to these people in this thread, no matter how right they are you probably don't have the pre-requisite knowlege to understand what they are saying or interpret it correctly. It might take a while, but if you are actually serious about understanding quantum computing go through the videos in this guys playlist. link to this video

I found this an excellent introduction to the subject. Very approachable, no higher level math. EDIT: That's a playlist of 22 videos (It looks like just 1 with RES).
