Generation of an optical Schrödinger-cat-like state in a non-ideal cavity by injecting opposite-phase atomic dipoles
Daeho Yang, Junki Kim, Moonjoo Lee +2
We propose a method to generate an optical Schrödinger-cat-like state in a cavity in a substantial decoherence regime. Even when the cavity decay rate is considerably large, a cat-…

Coherent and Dynamic Beam Splitting based on Light Storage in Cold Atoms
Kwang-Kyoon Park, Tian-Ming Zhao, Jong-Chan Lee +2
We demonstrate a coherent and dynamic beam splitter based on light storage in cold atoms. An input weak laser pulse is first stored in a cold atom ensemble via electromagnetically-…

Quantum coherence and population transfer in a driven cascade three-level artificial atom
Sung Un Cho, Han Seb Moon, Young-Tak Chough +2
We present an experimental investigation on the spectral characteristics of an artificial atom "transmon qubit" constituting a three-level cascade system (Ξ-system) in the presence…
