Realization of quantum decay control and Zeno dynamics in photonic structures

This work shows that engineered waveguide-based systems can be designed to control photon tunneling decay, providing an experimentally accessible laboratory tool to test the universal features of dynamical control via parametric modulations, recently proposed for quantum mechanical decay. This study demonstrates the realization of quantum decay control and Zeno dynamics in photonic structures. By a proper design of the structure, acceleration or deceleration the tunneling decay rate, as well as suppression of fractional, can be achieved.
