Vacuum Rabi oscillations in a macroscopic superconducting qubit oscillator system.
We have observed the coherent exchange of a single energy quantum between a flux qubit and a superconducting LC circuit acting as a quantum harmonic oscillator. The exchange of an energy quantum is known as the vacuum Rabi oscillation: the qubit is oscillating between the excited state and the ground state and the oscillator between the vacuum state and the first excited state. We also show tha...
متن کاملLarge Vacuum Rabi Splitting in a Single Nitride-Based Quantum WellMicrocavity
Here, we report a theoretical detailed study of Vacuum Rabi Splitting (VRS) in the system of Nitride Single Quantum Well (SQW) within a semiconductor microcavity. Distributed Bragg Reflectors (DBRs) containing ZnTe/ZnSe multilayers including GaAs microcavity and ( SQW at the center of microcavity, has been considered. Upper and lower exciton-polariton branches obtaine...
متن کاملQuantum vacuum radiation spectra from a semiconductor microcavity with a time-modulated vacuum Rabi frequency.
We develop a general theory of the quantum vacuum radiation generated by an arbitrary time modulation of the vacuum Rabi frequency of an intersubband transition in a doped quantum well system embedded in a planar microcavity. Both nonradiative and radiative losses are included within an input-output quantum Langevin framework. The intensity and the spectral signatures of the extra-cavity emissi...
متن کاملRabi oscillations and macroscopic quantum superposition states
A two-level atom interacting with a single radiation mode is considered, without the rotating-wave approximation, in the strong coupling regime. It is shown that, in agreement with the recent results on Rabi oscillations in a Josephson junction (Y. Nakamura, Yu. A. Pashkin and J. S. Tsai, Phys. Rev. Lett. 87, 246601 (2001)), the Rabi frequency is indeed proportional to first kind integer order ...
متن کاملDecoherence and Rabi oscillations in a qubit coupled to a quantum two - level system
In this paper we review some of our recent results on the problem of a qubit coupled to a quantum two-level system. We consider both the decoherence dynamics and the qubit’s response to an oscillating external field.
