Generation of maximally entangled states on a superconducting resonator-star QPU

Resonator-star quantum processing units (QPUs) are a promising architecture to enhance long-range and one-to-all connectivity. In the considered superconducting star-type topology, a distributed-element resonator is used as the central component to connect multiple qubits over large distances. In this talk, we present our experimental results on generating entangled states for this star-type topology. Furthermore, we investigate the variation of the entanglement fidelity when increasing the number of qubits. These results provide an outlook for the algorithm performance on the resonator-star architecture.
