Tunable coupling scheme for flux qubits at the optimal point (2005)
Niskanen, Antti O., Nakamura, Yasunobu, Tsai, Jaw-Shen
We discuss a practical design for tunably coupling a pair of flux qubits via the quantum inductance of a third high-frequency qubit. The design is particularly well suited for realizing a recently...
Circuit with small-capacitance high-quality Nb Josephson junctions (2003)
Watanabe, Michio, Nakamura, Yasunobu, Tsai, Jaw-Shen
We have developed a fabrication process for nanoscale tunnel junctions which includes focused-ion-beam etching from different directions. By applying the process to a Nb/(Al-)Al_2O_3/Nb trilayer, we...
