Decoherence by Quantum Telegraph Noise
Benjamin Abel, Florian Marquardt
We investigate the time-evolution of a charge qubit subject to quantum telegraph noise produced by a single electronic defect level. We obtain results for the time-evolution of the…

Measuring the size of a Schroedinger cat state
Florian Marquardt, Benjamin Abel, Jan von Delft
We propose a measure for the "size" of a Schroedinger cat state, i.e. a quantum superposition of two many-body states with (supposedly) macroscopically distinct properties, by coun…
