Improving the purity of one- and two-qubit gates by AC fields
Sigmund Kohler, Peter Hänggi
We investigate the influence of AC driving fields on the coherence properties of one- and two-qubit gate operations. In both cases, we find that for suitable driving parameters, th…
Universal Approach to Overcoming Nonstationarity, Unsteadiness and Non-Markovity of Stochastic Processes in Complex Systems
Renat M. Yulmetyev, Anatolii V. Mokshin, Peter Hänggi
In present paper we suggest a new universal approach to study complex systems by microscopic, mesoscopic and macroscopic methods. We discuss new possibilities of extracting informa…
Coherent charge transport through molecular wires: influence of strong Coulomb repulsion
Franz J. Kaiser, Michael Strass, Sigmund Kohler +1
We derive a master equation for the electron transport through molecular wires in the limit of strong Coulomb repulsion. This approach is applied to two typical situations: First,…
100 Years of Brownian motion
Peter Hänggi, Fabio Marchesoni
In the year 1905 Albert Einstein published four papers that raised him to a giant in the history of science of all times. These works encompass the photon hypothesis (for which he…
Transport suppression in heterostructures driven by an ac gate voltage
Miguel Rey, Michael Strass, Sigmund Kohler +2
We explore the possibility of inducing in heterostructures driven by an ac gate voltage the coherent current suppression recently found for nanoscale conductors in oscillating fiel…
Driven quantum transport on the nanoscale
Sigmund Kohler, Jörg Lehmann, Peter Hänggi
We explore the prospects to control by use of time-dependent fields quantum transport phenomena in nanoscale systems. In particular, we study for driven conductors the electron cur…
