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…
