Local and nonlocal observables in quantum optics
It is pointed out that there exists an unambiguous definition of locality that enables one to distinguish local and nonlocal quantities. Observables of both types coexist in quantum optics, but one must be very careful when attempting to measure them. A nonlocal observable that formally depends on t...
