Creating and detecting micro-macro photon-number entanglement by amplifying and deamplifying a single-photon entangled state

We propose a scheme for the observation of micro-macro entanglement in photon number based on amplifying and deamplifying a single-photon entangled state in combination with homodyne quantum state tomography. The created micro-macro entangled state, which exists between the amplification and deampli...
