Trapping and coherent manipulation of a Rydberg atom on a microfabricated device: a proposal [PDF]
, 2005 We propose to apply atom-chip techniques to the trapping of a single atom in a circular Rydberg state. The small size of microfabricated structures will allow for trap geometries with microwave cut-off frequencies high enough to inhibit the spontaneous ...

Optimal control for generating excited state expansion in ring potential
Open Physics, 2020 We applied an optimal control algorithm to an ultra-cold atomic system for constructing an atomic Sagnac interferometer in a ring trap. We constructed a ring potential on an atom chip by using an RF-dressed potential.

Tunable one-dimensional microwave emissions from cyclic-transition three-level atoms [PDF]
, 2010 By strongly driving a cyclic-transition three-level artificial atom, demonstrated by such as a flux-based superconducting circuit, we show that coherent microwave signals can be excited along a coupled one-dimensional transmission line.

Quantum state reconstruction on atom-chips
New Journal of Physics, 2015 We realize on an atom-chip, a practical, experimentally undemanding, tomographic reconstruction algorithm relying on the time–resolved measurements of the atomic population distribution among atomic internal states.

Microwave quantum optics with an artificial atom in one-dimensional open space
New Journal of Physics, 2013 We address recent advances in microwave quantum optics with artificial atoms in one-dimensional (1D) open space. This field relies on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a 1D open ...
