MCAIM Graduate Seminar Seminar

Control of closed (Hamiltonian) quantum systems has been widely studied in the last few decades from both theoretical and interdisciplinary points of view. Recently, there has been a growing interest in control of open (dissipative, non-Hamiltonian) quantum systems because of their applications to physics, chemistry and quantum computing. In this talk, we will give an introduction to the control of open quantum systems, specializing to the case of the qubit: a 2-level quantum system widely studied in quantum computing and other applications. In particular, we will focus on mathematical tools used to describe and manipulate decoherence, which we will identify as the effect on a quantum state due to interactions with the environment.
