I’m having a little difficulty understanding the difference between pure states and mixed states.(adsbygoogle = window.adsbygoogle || []).push({});

Given a physical system and its associated Hilbert Space, is each member (or ray) of the Hilbert Space always a?pure state

Is every linear combination (sum or integral) of pure states in the Hilbert Space always a?pure state

Thank you in advance.
