| contents | A molecular MCB junction in the partially wet phase has been used to probe effects related to open quantum systems. Although the exact quantum system, environment, and coupling, are not known the nature of the experiments shows a measurement influenced next measurement. The quantum system senses the measurement outcome and prepares itself in a state other than the state related to the measurement outcome. This triggers an alternation of measurements which are indicative of two current carrying states. In case three or more current carrying states are observed, there exists a fixed sequence of states that carry the current. We conclude that memory effects in these systems are responsible for these experimental observations. |
