Superposition of macroscopically distinct states means large multipartite entanglement
Tomoyuki Morimae
We show relations between superposition of macroscopically distinct states and entanglement. These relations lead to the important conclusion that if a state contains superposition…

Necessity of macroscopic operation for the creation of superpositions of macroscopically distinct states
Tomoyuki Morimae
We consider the creation of superpositions of macroscopically distinct states by a completely-positive (CP) operation on a subsystem. We conclude that the subsystem on which the CP…
