Maintaining a quantum superposition state of light in a cavity has important applications for quantum error correction. We demonstrate an experimental protocol based on parametric pumping and Josephson circuits, which prepares a Schrodinger cat state in a cavity. This is achieved by engineering a dissipative environment, which exchanges only pairs of photons with our cavity mode. The dissipative nature of this preparation would lead to the observation of a dynamical Zeno effect, where the competition between a coherent drive and the dissipation reveals non trivial dynamics.
