Schrdinger’s cat paradox has revealed the entanglement between microscopic and macroscopic objects. Recently, several approaches have been proposed to generate such hybrid entangled state. In this paper, we demonstrate the generation of generalized hybrid entangled state in a cavity electro–optic system. The hybrid entangled state between the optical cavity and the microwave field is generated by a one-step evolution. Numerical simulations show that the high-fidelity entangled state is obtained even if the decay of the system is considered. Also, this proposal can be applied to generate macroscopic quantum superposition states of the microwave field.

腔电光系统中广义混合纠缠的产生

薛定inger的猫悖论揭示了微观和宏观物体之间的纠缠。最近，已经提出了几种方法来产生这种混合纠缠态。在本文中，我们证明了腔电光系统中广义混合纠缠态的产生。光腔与微波场之间的混合纠缠状态是通过一步发展来产生的。数值模拟表明，即使考虑系统的衰减，也可以获得高保真纠缠态。而且，该建议可以应用于生成微波场的宏观量子叠加状态。
