Analysis of a tuneable coupler for superconducting phase qubits

Understand

This paper presents a theoretical analysis of the recently realized tuneable coupler for superconducting phase qubits (R.

• The coupling can be turned off by compensating a negative mutual inductance with a tuneable Josephson inductance.
