Demonstration of Entangling Gate for All-to-All Connected Superconducting Qubits

ORAL

Abstract

Exploring highly connected networks of qubits is invaluable for implementing various quantum codes and simulations. All-to-all connectivity allows for entangling qubits with reduced gate depth. In the ion community, the Mølmer-Sørensen gate is routinely used to entangle over a dozen qubits with high fidelity. We demonstrate a Mølmer-Sørensen-like interaction through the use of shared coplanar waveguide (CPW) resonators to couple multiple superconducting qubits and analyze the effect of qubit lifetimes in the Rabi dressed frame on our gate fidelity.
