We consider a quantum harmonic oscillator initially prepared in a Schroedinger cat state and interacting with its environment. We show that the environment induced decoherence transforming the cat state into a statistical mixture can be strongly inhibited by means of appropriate sequences of measurements.7 pages, 3 figuresQuantum Physicstext
