Superconducting quantum bit based on the Cooper pair box
The more advanced proposals so far for the implementation of qubits and quantum gates for quantum computation are based on ions or atoms in vacuum [2, 3]. These systems have been manipulated individually in a controlled fashion for about 20 years and techniques have reached a high level of sophistication. However, it is not clear yet if these proposals can be extended to the fabrication of a quantum processor which would be “scalable”, a jargon term referring to the situation where fabrication costs scale sufficiently ”gently” with the number of quantum bits and gates that quantum computation can overpower its classical counterpart.
