WebThe overall phase of a system’s quantum state is an unmeasurable quantity that can be freely assigned. However, when the system is driven slowly in a cycle, it undergoes an adiabatic evolution which may bring its final state back to the initial one (1, 2); the accumulated phase then becomes gauge invariant and, therefore, detectable.As noted …
