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…

Visualization of superposition of macroscopically distinct states
Tomoyuki Morimae, Akira Shimizu
We propose a method of visualizing superpositions of macroscopically distinct states in many-body pure states. We introduce a visualization function, which is a coarse-grained quas…
