Dear all
Please be informed about the following QSIT Seminar.
With best regards, Ilona Blatter --------------------------------------------------- Date: Tuesday, November 1, 2011 Time: 11:00 Place: HPF G 6 Host: Andreas Wallraff
Working with multipartite entanglement in real systems Jens Siewert Universidad del País Vasco, Bilbao, Spain
In this talk I will present briefly two topics of ongoing research regarding the generation and detection of multipartite entanglement. In the first part, I will explain an idea how multipartite entanglement could be generated in a circuit-QED system with many qubits (N > 10) and, in particular, how this entanglement could be detected and investigated systematically. The second topic of my presentation focuses on a new method to quantify tripartite entanglement in three-qubit states. This method is suitable to compute the so-called three-tangle for mixed states and gives exact values for a large family of states with a certain symmetry, while for all other states it yields a nontrivial lower bound.
