BACKWARD CAUSALITY AND THE APPARENT TIME IRREVERSIBILITY OF MEASUREMENT: A POSSIBLE RESOLUTION
Giuseppe Castagnoli
The notion of the coexistence in the quantum framework of causality forward or backward in time is proposed as a possible way for solving the problem of measurement.

MEASUREMENT, IRREVERSIBILITY AND DECOHERENCE IN QUANTUM MECHANICS
Belal Ehsan Baaquie
We review Prigogine's model of quantum measurement. The measuring apparatus is considered to be an unstable quantum system with its state vector belonging to a rigged Hilbert space. Time irreversibility arises due to the dissipative nature of the measuring apparatus (an unstable quantum system) which induces decoherence in the system being measured. Friedrichs' model is used to concretely illustrate these ideas.
