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…
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.…
Fast pulsed photoemission from a double quantum well on a dielectric substrate as a dynamic process of inverse LEED leading to the generation of a charge and current density wave
Yu. G. Peisakhovich, A. A. Shtygashev
Within the framework of the rigorous quantum theory of the atomic photoeffect and the scenario of photoemission from a crystal as an inverse LEED process, pulsed photoemission from…
Quantum correlations of the photon fields in a waveguide quantum electrodynamics
Ya. S. Greenberg. O. A. Chuikin, A. G. Moiseev, A. A. Shtygashev
We present a time-dependent quantum calculations of the first order and second order photon correlation functions for the scattering of a single-photon pulse on a two-level atom (q…
Single-photon scattering on a two-qubit system. Spatio-temporal structure of the scattered field
Ya. S. Greenberg, A. A. Shtygashev, A. G. Moiseev
In this paper, we study the spatiotemporal distribution of the photon electric field produced by the scattering of a single photon narrow pulse from a system of two identical qubit…
Dynamical theory of single-photon transport through a qubit chain coupled to a one-dimensional nanophotonic waveguide
Ya. S. Greenberg, O. A. Chuikin, A. A. Shtygashev +1
We study the dynamics of a single-photon pulse travelling through a linear qubit chain coupled to continuum modes in a one-dimensional (1D) photonic waveguide. We derive a time-dep…
Quantum phase measurement for two-qubit states in an open waveguide
Ya. S. Greenberg, A. A. Shtygashev
We present a new method for quantum state tomography within a single-excitation subspace of two-qubit states in an open waveguide. The system under investigation consists of three…
Single-photon scattering on a qubit. Space-time structure of the scattered field
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…
Spontaneous decay of artificial atoms in a three-qubit system
Ya. S. Greenberg, A. A. Shtygashev, A. G. Moiseev
We study the evolution of qubits amplitudes in a one-dimensional chain consisting of three equidistantly spaced noninteracting qubits embedded in an open waveguide. The study is pe…
Spontaneous decay of artificial atoms in a multi-qubit system
Ya. S. Greenberg, A. A. Shtygashev, A. G. Moiseev
We consider a one-dimensional chain of N equidistantly spaced noninteracting qubits embedded in an open waveguide. In the frame of single-excitation subspace, we systematically stu…
