Abstract
The concept of quantum information in a state is analysed. For a component of an entangled state, the potential measurements are claimed to define a c ontest, against which the information is to be interpreted. Projective meas urements are shown to allow the processing of information contained in the incoming quantum states. Finally the process of a quantum measurement is co nsidered as a mapping between different parts of the system, a quantum info rmation transfer.
