Four-qubit device with mixed couplings
M. Grajcar, A. Izmalkov, S. H. W. van der Ploeg +12
We present the first experimental results on a device with more than two superconducting qubits. The circuit consists of four three-junction flux qubits, with simultaneous ferro- a…

Mediated tunable coupling of flux qubits
Alec Maassen van den Brink, A. J. Berkley, M. Yalowsky
It is sketched how a monostable rf- or dc-SQUID can mediate an inductive coupling between two adjacent flux qubits. The nontrivial dependence of the SQUID's susceptibility on exter…
