Causation between states or only between measurements?

  1. Jun 18, 2013 #1
    In the use of the word "causation" can one say that one quantum state "causes" another if the two states are not measured? Or does the concept of causation only refer to a relationship between measurements?

    A quantum state at time t=0 can evolve into a different state at t=T. In that case the first state clearly "caused" the second state.
