| Abstract: | A scheme is proposed to controll the decoherence ofthree-level rf-SQUID qubit with asymmetric potential by designing anexternal electric circuit for superconductive flux qubit. Theresults show that it may not only raise the gate speed but also extenddecoherence time for a three-level structure. |
| Keywords: | gate speed quantum NOT gates decoherence time controll |
