Improving the purity of one- and two-qubit gatesSigmund Kohler and Peter HänggiFortschr. Phys. 54, 804 (2006) We investigate the influence of AC driving fields on the coherence properties of one- and two-qubit gate operations. In both cases, we find that for suitable driving parameters, the gate purity improves significantly. A mapping of the time-dependent system-bath model to an effective static model provides analytical results. The resulting purity loss compares favorably with numerical results. arXiv:quant-ph/0509085 |
