Macroscopic Optomechanical Superpositions via Periodic Qubit Flipping

Seminar

In this talk, we will discuss a scheme to generate macroscopic superpositions of well-distinguishable coherent states of an end mirror in an optomechanical system via periodic qubit flipping. Our scheme does not require the single-photon strong-coupling rate of an optomechanical system. The generated mechanical superposition state can be reconstructed using mechanical quantum-state reconstruction. The proposed scheme relies on recycling of an atom, fast atomic qubit flipping, and state mapping between a single-photon superposition state and an atomic superposition state. We will also discuss the experimental feasibility of our proposal under current technology.
