Quantum bits with electric charges by Josephson junction

Suzuki R, Saito H, Yamaguchi T, Sugiyama A, Sakamoto I, Nagao H, Nishikawa K

Recently, K.Ch.Chatzisavvas et al. have proposed the one- and two-qubit device by means of Josephson junction. In this work, we extend their work to realize the three-qubit device, and construct explicitly the CCNOT gate of the three-qubit device.
