Interaction and entanglement engineering in driven giant atoms setup with coupled resonator waveguide
We investigate the coherent interactions mediated by the coupled resonator waveguide between two types of giant atoms. We find that the effective coupling and collective dissipation can be controlled on demand by adjusting the configuration of the giant atoms. As a result, the external driving gives...

Summary: | We investigate the coherent interactions mediated by the coupled resonator
waveguide between two types of giant atoms. We find that the effective coupling
and collective dissipation can be controlled on demand by adjusting the
configuration of the giant atoms. As a result, the external driving gives birth
to a substantial entanglement between two giant atoms, which exhibits a Rabi
splitting character. {In the three giant atom setup, we find that the nonzero
next neighbour atomic entanglement can surpass the neighbour ones, and is able
to be adjust by tuning the driving phase, which serves as an artificial
magnetic field. The enhancement of next neighbour atomic entanglement can not
be realized in the small atom setup.} We hope these controllable interactions
in giant atom array are of great applications in the quantum information
process. |
