ENTANGLEMENT OF SUPERPOSITION OF MULTI-STATES
Songsong Li, Yibin Huang · International Journal of Quantum Information · 2008
In this letter, we investigate the entanglement of superposition of multi-states. Three cases are considered when the states in the superposition are mutually biorthogonal, mutually orthogonal and nonorthogonal. The relations between the entanglement of superposition and the entanglements of the superposed states are explored.
