Bounds on Compositeness from Neutrinoless Double Beta Decay

Assuming the existence of a heavy Majorana neutral particle arising from a composite model scenario we discuss the constraints imposed by present experimental limits of half-life neutrinoless double beta decay $(0\nu\beta\beta )$ measurements on the coupling of the heavy composite neutrinos to the gauge bosons. For neutrino masses $M_N = 1$ TeV we obtain a rather weak lower bound on the compositeness scale: $\Lambda \ge 0.23$ TeV.Comment: Plain Latex file, 15 pages; 3 figures appended as a uuencoded file; misprint corrected in titlepag

Quantum Nondemolition Charge Measurement of a Josephson Qubit

In a qubit system, the measurement operator does not necessarily commute with the qubit Hamiltonian, so that the readout process demolishes (mixes) the qubit energy eigenstates. The readout time is therefore limited by such a mixing time and its fidelity will be reduced. A quantum nondemolition readout scheme is proposed in which the charge of a flux qubit is measured. The measurement operator is shown to commute with the qubit Hamiltonian in the reduced two-level Hilbert space, even though the Hamiltonian contains non-commuting charge and flux terms.Comment: 4 pages, 3 figures, a paragraph added to describe how the scheme works in charge regim
