Abstract:Utilizing a current-biased Josephson junction (CBJJ) as a tunable coupler for superconducting transmission line resonators (TLRs), we propose a potentially practical scheme to create entangled coherent states of the two TLR modes. Then, the influence of TLRs decay on the prepared entangled states is analyzed. And an interesting phenomenon that even entangled coherent states are robustness against decay with small a is found. At last, the experimental feasibility and the challenge of our schemes have been discussed. (C) 2012 Elsevier B.V. All rights reserved.
