We show that a system of polaritons-combined atom and photon excitations-in an array of coupled cavities, under an experimental setup usually considered in electromagnetically induced transparency, is described by the Bose-Hubbard model. This opens up the possibility of using this system as a quantum simulator, allowing for the observation of quantum phase transitions and for the measurement of...
