Name: What's so special about entangled states anyway?
Uploaded: 2010-11-26
Description: What makes an entangled state different from an ordinary joint description? Michael Nielsen explores that question within his course sequence. This is a follow-on to Bell-state preparation for viewers ready to examine structure rather than stop at the word 'connected.' Shared notation helps make the comparison meaningful.
