Entangling Movable Mirrors Both field-mirror pairs coupled in a DCP Field-mirror pairs coupled one in a DCP and one in BSP or vice verse. No entanglement between movable mirrors because of effective BSP Both field-mirror pairs coupled in a BSP Effective DCP with a large stable region. Entangled! They do not generate entanglement between mirrors because of instability!
