Description
Summary:► Quantum Zeno effect may be induced by the environment in coupled microwave modes. ► Two regimes are found, only one of them exhibits the Quantum Zeno effect. ► The key point is the relation between a dissipation constant and unitary coupling. ► The effect may be verified within todays experimental reach. We model a feasible experiment involving two interacting microwave cavities with very different quality factors. An excitation is initially present in the high Q cavity. Modeling the environment as linearly coupled oscillators, we find a Zeno-like behavior which should occur when the dissipation constant is large enough as compared to the unitary coupling.
