Creating and probing macroscoping entanglement with light
We describe a scheme showing signatures of macroscopic optomechanical
entanglement generated by radiation pressure in a cavity system with a massive
movable mirror. The system we consider reveals genuine multipartite
entanglement. We highlight the way the entanglement involving the inaccessible
massive object is unravelled, in our scheme, by means of field-field quantum
correlations.Comment: 4 pages, 5 figure, RevTeX
Stationary entanglement between two movable mirrors in a classically driven Fabry-Perot cavity
We consider a Fabry-Perot cavity made by two moving mirrors and driven by an
intense classical laser field. We show that stationary entanglement between two
vibrational modes of the mirrors, with effective mass of the order of
micrograms, can be generated by means of radiation pressure. The resulting
entanglement is however quite fragile with respect to temperature.Comment: 15 pages, 3 figure
