Quantum state preparation in circuit QED via Landau-Zener tunnelingKeiji Saito, Martijn Wubs, Sigmund Kohler, Peter Hänggi, and Yosuke KayanumaEurophys. Lett. 76, 22 (2006) 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 nonadiabatic transition probability for the qubit, being independent of the frequency of the QED mode. Possible applications are single-photon generation and the controllable creation of qubit-oscillator entanglement. arXiv:cond-mat/0603188 |
