When is there a multipartite maximum entangled state?
Keyword(s):
For a multipartite quantum system of the dimension $d_1\otimes d_2\otimes\cdots\otimes d_n$, where $d_1\ge d_2\ge\cdots\ge d_n\ge2$, is there an entangled state {\em maximum} in the sense that all other states in the system can be obtained from the state through local quantum operations and classical communications (LOCC)? When $d_1\ge\Pi_{i=2}^n d_i$, such state exists. We show that this condition is also necessary. Our proof, somewhat surprisingly, uses results from algebraic complexity theory.
