Coherent dynamics of a Josephson charge qubit

Delsing and co-workers have developed an rf-SET (radio frequency single-electron transistor) readout for the charge qubit, i.e. the single Cooper-pair box (SCB) two-level system, and successfully detected free oscillations and studied the detailed behaviour of relaxation and de-phasing. A major task and activity at Chalmers has been to investigate the coherence and mixing times for the charge qubit. This is described in detail in an extensive paper accounting for the Chalmers work on the single Cooper-pair box as a charge qubit using dc-pulse operation and RF-SET detection.
