Dynamics of dispersive single qubit read-out in circuit quantum electrodynamics
The quantum state of a superconducting qubit nonresonantly coupled to a
transmission line resonator can be determined by measuring the quadrature
amplitudes of an electromagnetic field transmitted through the resonator. We
present experiments in which we analyze in detail the dynamics of the
transmitted field as a function of the measurement frequency for both weak
continuous and pulsed measurements. We find excellent agreement between our
data and calculations based on a set of Bloch-type differential equations for
the cavity field derived from the dispersive Jaynes-Cummings Hamiltonian
including dissipation. We show that the measured system response can be used to
construct a measurement operator from which the qubit population can be
inferred accurately. Such a measurement operator can be used in tomographic
methods to reconstruct single and multiqubit states in ensemble-averaged
measurements.Comment: Revised version: corrected typos, 8 pages, 6 figures, version with

An alternative search for the electron capture of Te-123
A search for the electron capture of Te-123 has been performed using CdZnTe
detectors. After a measuring time of 195 h no signal could be found resulting
in a lower half-life limt of yrs (95 % CL) for
this process. This clearly discriminates between existing experimental results
which differ by six orders of magnitude and our data are in strong favour of
the result with longer half-lifes.Comment: 2 pages, 2 eps-figures, reanalysis of data set
