  Dempster-Shafer evidence theory is wildly applied in multi-sensor data
fusion. However, lots of uncertainty and interference exist in practical
situation, especially in the battle field. It is still an open issue to model
the reliability of sensor reports. Many methods are proposed based on the
relationship among collected data. In this letter, we proposed a quantum
mechanical approach to evaluate the reliability of sensor reports, which is
based on the properties of a sensor itself. The proposed method is used to
modify the combining of evidences.
