Repeated and continuous interactions in open quantum systems
We consider a finite quantum system S coupled to two environments of different nature. One is a heat reservoir R (continuous interaction) and the other one is a chain C of independent quantum systems E (repeated interaction). The interactions of S with R and C lead to two simultaneous dynamical processes. We show that for generic such systems, any initial state approaches an asymptotic state in...
متن کاملEntanglement of Bipartite Quantum Systems driven by Repeated Interactions
We consider a non-interacting bipartite quantum system HA S ⊗ HB S undergoing repeated quantum interactions with an environment modeled by a chain of independant quantum systems interacting one after the other with the bipartite system. The interactions are made so that the pieces of environment interact first with HA S and then with HB S . Even though the bipartite systems are not interacting,...
متن کاملRepeated Interaction Quantum Systems
We consider a quantum system interacting sequentially with elements of a chain of independent quantum subsystems. We treat two kinds of such repeated interaction systems: deterministic and random ones. In both cases we show that, under suitable conditions, the system approaches an asymptotic state in the large time limit, and we construct that state. Our methods are based on the analysis of pro...
متن کاملRepeated Quantum Interactions and Unitary Random Walks
Among the discrete evolution equations describing a quantum system HS undergoing repeated quantum interactions with a chain of exterior systems, we study and characterize those which are directed by classical random variables in RN . The characterization we obtain is entirely algebraical in terms of the unitary operator driving the elementary interaction. We show that the solutions of these equ...
متن کاملFrom repeated to continuous quantum interactions
We consider the general physical situation of a quantum system H0 interacting with a chain of exterior systems ⊗IN∗H, one after the other, during a small interval of time h and following some Hamiltonian H on H0 ⊗H. We discuss the passage to the limit to continuous interactions (h → 0) in a setup which allows to compute the limit of this Hamiltonian evolution in a single state space: a continuo...
