A Curious Geometrical Fact About Entanglement

Quantum Physics 2009-11-13 v1

Abstract

I sketch how the set of pure quantum states forms a phase space, and then point out a curiousity concerning maximally entangled pure states: they form a minimal Lagrangian submanifold of the set of all pure states. I suggest that this curiousity should have an interesting physical interpretation.
