Landau-Zener transitions in qubits controlled by electromagnetic fields
Martijn Wubs, Keiji Saito, Sigmund Kohler +2
We investigate the influence of a dipole interaction with a classical radiation field on a qubit during a continuous change of a control parameter. In particular, we explore the no…
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,…
Nonadiabatic Electron Pumping: Maximal Current with Minimal Noise
Michael Strass, Peter Hänggi, Sigmund Kohler
The noise properties of pump currents through an open double quantum dot setup with non-adiabatic ac driving are investigated. Driving frequencies close to the internal resonances…
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…
Coherence stabilization of a two-qubit gate by AC fields
Karen M. Fonseca Romero, Sigmund Kohler, Peter Hänggi
We consider a CNOT gate operation under the influence of quantum bit-flip noise and demonstrate that ac fields can change bit-flip noise into phase noise and thereby improve cohere…
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…
