Conductance of a hydrogen molecule
J. Heurich, F. Pauly, J. C. Cuevas +2
Recently Smit et al. [Nature 419, 906 (2002)] have reported that a single hydrogen molecule can form a bridge between Pt electrodes, which has a conductance close to one quantum un…
Quantum state engineering with Josephson-junction devices
Yuriy Makhlin, Gerd Schoen, Alexander Shnirman
We review recent theoretical and experimental progress in quantum state engineering with Josephson junction devices. The concepts of quantum computing have stimulated an increased…
Josephson-Junction Qubits and the Readout Process by Single-Electron Transistors
Yuriy Makhlin, Gerd Schoen, Alexander Shnirman
Several physical realizations of quantum bits have been proposed. Of those, nano-electronic devices appear most suitable for large-scale integration and potential applications. We…
Quantum Measurements Performed with a Single-Electron Transistor
Alexander Shnirman, Gerd Schoen
Low-capacitance Josephson junction systems as well as coupled quantum dots, in a parameter range where single charges can be controlled, provide physical realizations of quantum bi…
A New Quantum Phase Transition in the Coupled Quantum Dots System
Natan Andrei, Gergely T. Zimanyi, Gerd Schoen
We study two quantum dots in the limit of strong dot-lead coupling and weak dot-dot tunneling. The model maps on Ising-coupled Kondo impurities. We argue that a new quantum critica…
