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 کاملA THEORY OF VACUUM TUNNELING MICROSCOPY1
A theory for tunneling between a real surface and a model probe tip, applicable to the "scanning tunneling microscope" is presented. The tunneling current is found to be proportional to the local density of states of the surface, at the position of the tip. It can be shown that the tunneling conductance has exponential dependence on the distance of the nearest approach to the surface
متن کاملObservation of the vacuum Rabi spectrum for one trapped atom.
The transmission spectrum for one atom strongly coupled to the field of a high finesse optical resonator is observed to exhibit a clearly resolved vacuum Rabi splitting characteristic of the normal modes in the eigenvalue spectrum of the atom-cavity system. A new Raman scheme for cooling atomic motion along the cavity axis enables a complete spectrum to be recorded for an individual atom trappe...
متن کاملVacuum Evacuation Effect on Ichiro 9cell Cavities during Vertical Test
We have continued high gradient R&D of ICHIRO 9cell cavities at KEK. The maximum gradient of ICHIRO 9-cell cavity #5 that has no end group on beam tubes was still limited around 36MV/m so far. The 9-cell performances were sometimes limited by triggered field emission (FE) by multipactings. We suspected the residual gas in the cavity might be one of the sources of triggered FE. The cavity was cl...
متن کاملVacuum Rabi splitting for multilevel electromagnetically induced transparency system
We discuss the vacuum Rabi splitting (VRS) from multilevel atoms under electromagnetically induced transparency condition within the framework of linear absorption-dispersion theory. Sharp resonance features superimposed on usually occurring VRS doublet to three-peaked structure spectra are obtained here which can be engineered to have absorptive, dispersive, or dip like profiles according to t...
