Dynamics of Quantum Correlations in Open Quantum Systems

Date: Tuesday, July 06, 4:30pm-6:00pm
Speaker: Dr. Bruno BELLOMO Univ. Palermo, Italy
Title: Dynamics of Quantum Correlations in Open Quantum Systems
Room: 55S-02-Conference Room No. 3
Quantum correlations in composite systems lie at the heart of quantum mechanics and play a fundamental role in protocols of quantum information and computation. Environmental effects on the dynamics of quantum systems are ubiquitous and typically lead to loss of correlations in open quantum systems.
In this talk I review the dynamics of different features of quantum correlations, ranging from entanglement to nonlocality, in several configurations of composite systems made by qubits embedded in structured environments [1-6]. The roles of environmental spectral properties, interactions and initial preparation of the systems are pointed out.
