Decoherence and coherent coupling of electrons in Penning traps — •Carsten Henkel and Jorge R. Zurita Sánchez — Institut für Physik, Universität Potsdam, Germany

We consider electrons in Penning traps and estimate the time scales available for coherent manipulations on the cyclotron and axial degrees of freedom. Thermal excitations from the metallic electrodes are shown to be negligible at low temperature. A model for the quantum fluctuations due to the circuitry connected to the electrodes is developed. The interconnection of two traps by a transmission line is explored for a two-qubit gate implementation.
