Generation of W state and NOON state of distant polar molecules ensembles via a triple hybrid device

A scheme is proposed to generate the W state and NOON state for the collective molecular modes of distant polar molecules ensembles via a triple hybrid device. Through the virtual excitation of the microwave photons of the transmission-line resonators, the interaction between the superconducting charge qubit and the polar molecules induces the entanglement for the collective modes of the polar molecules. The enhanced effective coupling strength between the superconducting charge qubit and the polar molecules enables to generate the W state and NOON state with high fidelity.
