Conversion of thermal equilibrium states into superpositions of macroscopically distinct states

Conversion of thermal equilibrium states into superpositions of macroscopically distinct states
Akira Shimizu, Mamiko Tatsuta
A simple procedure for obtaining superpositions of macroscopically distinct states is proposed and analyzed. We find that a thermal equilibrium state can be converted into such a state when a single global measurement of a macroscopic observable, such as the total magnetization, is made. This method...
