Nov 27, 2020 at 2:04 comment added Michael Engelhardt $A$ is conserved in the sense that one can measure it repeatedly, as often as one likes, and one will always obtain the same result, corresponding to one of its eigenvalues (as long as one doesn't otherwise disturb the system between measurements, of course).

Jan 22, 2010 at 4:03 comment added Aaron Bergman It might be a little clearer to the asker to say that the expectation value of A in any state is conserved. Thus, the conserved quantity associated to the identity operator is 1.
Jan 22, 2010 at 3:57 comment added Mariano Suárez-Álvarez Hmm. Isn' the conserved quantity $A$ itself?
