Proposal for exploring macroscopic entanglement with a single photon and coherent states
Proposal for exploring macroscopic entanglement with a single photon and coherent states
Entanglement between macroscopically populated states can easily be created by combining a single photon and a bright coherent state on a beamsplitter. Motivated by the simplicity of this technique, we report on a method using displacement operations in the phase space and basic photon detections to reveal such an entanglement. …
