ABSTRACT
Josephson junction qubits are expected to be scalable within current lithography technology developed by the semiconductor industry. The resulting qubits are different from qubits in other realizations in that they are made up of a large number of particles (electrons in the present case) forming a mesoscopic condensate. Moreover, zero registance of superconducting metallic part implies the absence of dissipation. These facts, enhanced by a very low operating temperature, lead to the expectation that they are potentially robust against external noise and decoherence.
