Entangled Photon‐Magnon Bundle Emission

AbstractMultiquanta correlation between quanta of a completely different nature is an important resource for hybrid quantum information processing since it allows quantum states of matters to be manipulated by other degrees of freedom. Here, a method is proposed to realize the hybrid bundle emission of strongly correlated single photons and magnons. The optically driven multiquanta resonance leads to the super‐Rabi oscillation between the vacuum state and photon‐magnon state, which, combined with system dissipations, generates photon‐magnon bundle emission. Interestingly, accompanied by this bundle emission, the photon‐magnon entanglement and fully inseparable photon‐magnon‐qubit tripartite entanglement are achieved. This allows the proposed hybrid system to serve as a quantum emitter of entangled photon‐magnon bundle, which is useful for building hybrid quantum network and the engineering of new types of quantum devices.
