Tunable coupling of superconducting qubits
Alexandre Blais, Alec Maassen van den Brink, A. M. Zagoskin
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 ca…

Multi-Terminal Superconducting Phase Qubit
M. H. S. Amin, A. N. Omelyanchouk, A. Blais +4
Mesoscopic multi-terminal Josephson junctions are novel devices that provide weak coupling between several bulk superconductors through a common normal layer. Because of the nonloc…

Quantum-efficient charge detection using a single-electron transistor
Alec Maassen van den Brink
We evaluate the detector nonideality (and energy sensitivity) of a normal-state single-electron transistor (SET) in the cotunneling regime in a two-charge-state approximation. For…
