Summary, Etc.  

요약We explore procedures to approximate the reduced dynamics of open qubit systems, to understand the construction of effective open theories in more general systems. We provide constructions both for infinitesimal time-evolution i.e. master equations, and for discrete time-evolution through random ensembles of quantum channels. An argument is made that the ensemble approach is a much better suited method to tackle the open dynamics experienced in more novel open systems, such as those with time-dependent boundaries that are found in quantum cosmology. We also explore the idea that quantum subsystems may appear through a process of spontaneous symmetry breaking, which serves as the prequel to the appearance of an open quantum system.
