We present an experimental demonstration of the Jaynes-Cummings-Hubbard model conducted using trapped ions. This model describes an array of coupled optical cavities, each containing a two-level atom, and is expected to exhibit properties peculiar to strongly correlated systems. Using the internal and radial phonon states of two trapped ions, the model is experimentally realized and quantum phase transition from a localized insulator state to a delocalized superfluid state is demonstrated. A superfluid phase of polaritonic excitations is also observed during the adiabatic transfer process.
