30 Jan 2016 | Abstract: | The study of open quantum systems is important for fundamental issues of
quantum physics as well as for technological applications such as quantum
information processing. The interaction of a quantum system with it’s
environment is usually detrimental for the quantum properties of the system and
leads to decoherence. However, sometimes a coherent partial exchange of
information takes place between the system and the environment and the dynamics
of the open system becomes non-Markovian. In this article we study discrete
open quantum system dynamics where single evolution step consist of local
unitary transformation on the open system followed by a coupling unitary
between the system and the environment. We implement experimentally a local
control protocol for controlling the transition from Markovian to non-Markovian
dynamics. | Source: | arXiv, 1602.0060 | Services: | Forum | Review | PDF | Favorites |
