Establishing quantum steerability on cavity arrays coupled by optical fibers with open boundary conditions

We study quantum steerability on one-dimensional cavity array systems with open boundary conditions, where each cavity is doped with a two-level atom and coupled with its neighbor nodes by optical fibers. In the far off-resonant condition, we obtain explicit expressions for the dynamical evolution o...

Zusammenfassung:We study quantum steerability on one-dimensional cavity array systems with open boundary conditions, where each cavity is doped with a two-level atom and coupled with its neighbor nodes by optical fibers. In the far off-resonant condition, we obtain explicit expressions for the dynamical evolution of the array system with arbitrary number of nodes. By investigating the steerable weight for two-node subsystems, we show that remote quantum steerability can be established through both single-array and double independent arrays. Moreover, comparisons between quantum steerability and quantum entanglement in this model are also examined.
