Completely Entangled State and Simultaneous Eigenstate in a Finite Dimensional Space
- 51 Downloads
It is shown that a completely entangled state belonging to a finite dimensional Hilbert space is equivalent to a simultaneous eigenstate of two unitary operators. These operators are exponentials of sum and difference of two Hermitian operators of a two-mode system that are complementary with each other.
