Multipartite entanglement mediated by shared microwave resonators

ORAL

Abstract

Developing highly connected networks of qubits is invaluable for implementing various quantum codes and simulations. Increased connectivity allows for entangling qubits with reduced gate depth. For example, the Mølmer-Sørensen gate generates high fidelity entanglement between multiple ions. We use shared coplanar waveguide (CPW) resonators to realize an analogous Mølmer-Sørensen gate between superconducting qubits. This talk describes how the CPW enables multipartite entanglement of all qubits coupled to the resonator as well as arbitrary subsets of qubits.
