Quantum state engineering by a coherent superposition of photon subtraction and addition

We study a coherent superposition ta+ra{sup {dagger} }of field annihilation and creation operators acting on continuous variable systems and propose its application for quantum state engineering. Specifically, it is investigated how the superposed operation transforms a classical state to a nonclass...
