Steady-state entanglement between hybrid light-matter qubits

Year: 2009

Type: article

Abstract: We study the case of two polaritonic qubits localized in two separate cavities coupled by a fiber/additional cavity. We show that classical driving of the intermediate cavity/fiber can lead to the creation of entanglement between the two ends in the steady state. The stationary nature of this entanglement and its survival under dissipation opens possibilities for its production under realistic laboratory conditions. To facilitate the verification of the entanglement in an experiment we also construct the relevant entanglement witness measurable by accessing only a few local variables of each polaritonic qubit.
