| Abstract: | The search for a quantum computer has been stimulated by the development of algorithms that would solve intractable problems (exponential time) if the massive parallel processing of the anticipated quantum computer were available. Foremost among these problems is the determination of the prime factors of a large integer. We discuss our studies of single Josephson junctions as the qubits of a quantum computer and present microwave spectroscopy results for both single and coupled pairs of Josephson junctions. In addition, we will give some preliminary results on escape rates from single and pairs of junctions. We will also briefly discuss the advantages and obstacles connected with the single Josephson-junction approach. | |
