Abstract: Information measures corresponding to the development of a system's wave and particle properties are derived. The formulism is extended to the spin 1/2 operators. For both cases pure states are shown to be the maximal information states.;Coherence which plays a crucial role in the information measures' definition is also found to be of paramount importance in the measurement process. With the aid of the "haunted measurement" gedankenexperiment it is shown that the incoherence introduced by the interaction between the measuring apparatus and the observed system can be removed thereby reversing the measurement process, obliterating any trace of its occurrence. This is a direct consequence of the quantum mechanical correlations between the two systems. Thus, such correlations previously thought to be significant only in the microscopic domain must be taken into account in the macroscopic realm for a proper description of the measuring process.;Haunted measurement versions of Wheeler's delayed choice experiment, Schrodinger's cat experiment and the EPR paradox are also discussed.
