摘要: The dynamics of a two-level system immersed in a dissipative environment can be described by its system Hamiltonian H and coupling operator L, both of which can be parametrized in terms of Pauli matrices.  In this talk, we propose other parametrization methods of H and L so that the resulting system matrices look simpler than that by means of Pauli matrices. The proposed parametrization methods make direct use of controllability and observability properties of the system matrices, reminiscent of the Kalman decomposition for linear quantum systems recently proposed.

 

 

简介:Prof. Guofeng Zhang received his B.Sc. degree and M.Sc. degree from Northeastern University, Shenyang, China, in 1998 and 2000 respectively. He received a Ph.D. degree in Applied Mathematics from the University of Alberta, Edmonton, Canada, in 2005. During 2005–2006, he was a Postdoc Fellow at the University of Windsor, Windsor, Canada. He joined the School of Electronic Engineering of the University of Electronic Science and Technology of China, Chengdu, China, in 2007. From April 2010 to December 2011 he was a Research Fellow at the Australian National University. He is currently an Associate Professor in the Department of Applied Mathematics at the Hong Kong polytechnic University. His research interests include quantum information and control, sampled-data control and nonlinear dynamics.
