Explicit generation of unitary transformations in a single atom or molecule
Ramakrishna, V.; Ober, R.; Sun, X.; Steuernagel, O.; Botina, J.; Rabitz, H. (2000)A constructive procedure for generating a prescribed unitary transform via the optically driven evolution of a multilevel atom is described. Assuming a clean separation of the coupled levels, the procedure employs the ... -
Spontaneous parametric down-conversion for an arbitrary monochromatic pump beam
Steuernagel, O.; Rabitz, H. (1998)Signal-idler photon-pairs generated in spontaneous parametric down-conversion are considered for the case of an arbitrary monochromatic pump beam. It is shown that the quantum correlations between the signal and idler ... -
Time-resolved quantum measurements using active detectors
Steuernagel, O.; Rabitz, H. (1998)Time-resolved quantum measurements using active detectors are analyzed. It is shown that the time-resolved observation of a quantum field leads to a mode mismatch between observed field and detection device that unavoidably ...
