Nonadiabatic electron heat pump
Miguel Rey, Michael Strass, Sigmund Kohler +2
We investigate a mechanism for extracting heat from metallic conductors based on the energy-selective transmission of electrons through a spatially asymmetric resonant structure su…
Limitation of entanglement due to spatial qubit separation
Roland Doll, Martijn Wubs, Peter Hanggi +1
We consider spatially separated qubits coupled to a thermal bosonic field that causes pure dephasing. Our focus is on the entanglement of two Bell states which for vanishing separa…
Gauging a quantum heat bath with dissipative Landau-Zener transitions
Martijn Wubs, Keiji Saito, Sigmund Kohler +2
We calculate the exact Landau-Zener transitions probabilities for a qubit with arbitrary linear coupling to a bath at zero temperature. The final quantum state exhibits a peculiar…
Coulomb blockade effects in driven electron transport
Franz J. Kaiser, Peter Hänggi, Sigmund Kohler
We study numerically the influence of strong Coulomb repulsion on the current through molecular wires that are driven by external electromagnetic fields. The molecule is described…
Quantum state preparation in circuit QED via Landau-Zener tunneling
Keiji Saito, Martijn Wubs, Sigmund Kohler +2
We study a qubit undergoing Landau-Zener transitions enabled by the coupling to a circuit-QED mode. Summing an infinite-order perturbation series, we determine the exact nonadiabat…
