Macroscopic Distinguishability Between Quantum States
... In the case of quantum phase transitions (QPTs) [4], which occur at zero temperature and are driven by purely quantum fluctuations, the study of the ground state fidelity has been first conducted on the examples of the Dicke and XY models [5]. Note that in this case, the ground states are pure quant ...
