摘要：
A measurement process needs a time duration in many actual cases, such as the measurement on atomic system by the electron shelving technique. If this timescale is deficient, the measurement would be incomplete. Here, we investigate the quantum Zeno effect by incomplete measurements. We show that an efficient freeze of the quantum state by incomplete measurements is available. And interestingly, this state freeze can be more significant than that obtained in the complete measurement case if the parameters of incomplete measurements are properly set.
