Quantum state engineering by a coherent superposition of photon subtraction and addition Conference Paper uri icon


  • We study a coherent superposition tâ+r↠of field annihilation and creation operator acting on continuous variable systems and propose its application for quantum state engineering. We propose an experimental scheme to implement this elementary coherent operation and discuss its usefulness to produce an arbitrary superposition of number states involving up to two photons. © 2011 American Institute of Physics.
