Fast Parametric Gates with Superconducting Qubits

ORAL

Abstract

We discuss a system with two transmon qubits coupled parametrically through a shared dc-SQUID coupler. The coupling can be tuned from nominally zero to up to more than 100 MHz. This coupling mechanism can be used to perform a two-qubit controlled Z-gate. We present the latest experiment results on the gate operation.
