Duality and quantum state engineering in cavity arrays

Nilakantha Meher, S. Sivakumar, Prasanta K. Panigrahi

A system of two coupled cavities with $N - 1$ photons is shown to be dynamically equivalent to an array of $N$ coupled cavities containing one photon. Every transition in the two cav…

Permutation symmetry and entanglement in quantum states of heterogeneous systems

Gururaj Kadiri, S Sivakumar

Permutation symmetries of multipartite quantum states are defined only when the constituent subsystems are of equal dimensions. In this work we extend this notion of permutation sy…
