摘　　要：Quantum mechanics imposes limits on measurement accuracy through quantum noise which typically has two components:First is the shot noise originating from vacuum fluctuations and referred to as the imprecision noise.Second is the quantum backaction originating from the“action”of the measurement back on the object being measured.

关 键 词：quantum typically VACUUM
