Quantum Rabi oscillations of a qubit strongly coupled to a one-dimensional waveguide
Ya. S. Greenberg, A. A. Shtygashev, O. A. Chuikin +2
We theoretically investigate quantum Rabi oscillations in a system consisting of a two-level atom (qubit) strongly coupled to a one-dimensional open waveguide. In contrast to conve…
Spontaneous emission of a three-level artificial atom in a one-dimensional open waveguide
O. A. Chuikin, Ya. S. Greenberg, O. V. Kibis
We study the dynamical and spectral characteristics of a quantum three-level ladder system, interacting with a continuous electromagnetic field in one-dimensional open waveguide. C…
Decay of transmon qubit in a broadband one-dimensional cavity
Ya. S. Greenberg, A. A. Shtygashev, O. V. Kibis
We investigate the decay dynamics of a three-level artificial atom, a superconducting transmon qubit, weakly coupled to a continuum of modes in a broadband, one-dimensional cavity.…

Ya. S. Greenberg, A. G. Moiseev, A. A. Shtygashev
We study the space-time structure of the scattered field induced by the scattering of a narrow single-photon Gaussian pulse on a qubit embedded in 1D open waveguide. For a weak exc…
