A new reconfigurable frequency cavity compatible with planar technology has been designed, manufactured and measured. An original tuning solution is proposed, based upon the insertion of vertical capacitive posts integrated within SIW cavities. One extremity each post connected to a floating metallic ring, located on substrate supporting cavity. The agility obtained once ring ground plane by short-circuited corresponding annular slot using surface actuators. Such combination volumetric...
The authors demonstrate a reduction of the dc polarizability cesium atom Rydberg states in 77-K environment utilizing microwave field dressing. results could be useful for stabilizing resonances against varying fields present near surfaces and potentially enabling development hybrid Rydberg-atom--superconducting-resonator quantum gates.
We demonstrate reduction of the dc polarizability Cesium atom Rydberg states in a 77 K environment utilizing microwave field dressing. In particular we reduce $52P_{3/2}$ which have resonances at 5.35 GHz to $51D_{5/2}$, suitable for interfacing atoms superconducting resonators cryogenic environment. measure using Magneto-Optical-Trap (MOT) loss spectroscopy. Using an off-resonant radio-frequency (RF) dressing coupling and $51D_{5/2}$ $ 52P_{3/2}$ over 80$\%$. Experimental findings are good...
