Suhail Zubairy" ], "categories": [ "quant-ph" ], "abstract": "We propose a method to deterministically prepare an arbitrary quantum state in a one-dimensional (1D) continuum by a shaped photon pulse. This method is based on time-reverse of the quantum emission process. We show that the desired quantum state such as Dicke or timed-Dicke state can be successfully prepared with very high fidelity even if the dissipation to the environment is nonnegligible and the pulse shaping is not perfect. This method is experimentally feasible in 1D waveguide-QED or circuit-QED system.", "revisions": [ { "version": "v1", "updated": "2018-04-19T22:03:13.000Z" } ], "analyses": { "keywords": [ "arbitrary quantum state", "shaped photon pulse", "one-dimensional continuum", "deterministic preparation", "quantum emission process" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
