Tunable coupling of superconducting qubits
A Blais, AM van den Brink, AM Zagoskin - Physical review letters, 2003 - APS
We study an LC circuit implemented using a current-biased Josephson junction (CBJJ) as a
tunable coupler for superconducting qubits. By modulating the bias current, the junction can …
