In this video we briefly discuss how to determine if a state is entangled or separable by looking at some simple examples, and give a hint to the existence of methods that allow us to not only determine if states are entangled, but also the level or degree of entanglement (entanglement measures), and how these are closely related to the Schmidt Decomposition.
This video is part of a series on quantum entanglement:
