The Quantum Library is a place where you can find videos explaining quantum principles. When watching a lecture or taking a quiz, you can always come back to this library to get a better understanding of the follow topics and more:
bra-ket notation - state decomposition - measurement - superposition - entanglement
The library is a collection of links to videos that form the background information for this course. Like a regular library, these resources are here for your reference. Some of these videos might also be used in the course at different moments where they are required. The links here will take you to The School of Quantum, which is a repository of videos on topics from quantum computing produced by QuTech Academy.
Whether you would like to "binge watch" all the of the content at once, or treat it like a snack-bar, please feel free to watch and use these as you wish.
