Long-range connectivity is one of the most sought-after features in superconducting quantum processors today. It enables more efficient circuit compilation, more compact encoding of logical qubits, and scalability beyond the single-chip, single-fridge limits; in quantum annealing specifically, it allows more efficient embedding of realistic optimization problems. In this talk, I will present two complementary work towards realizing long-range entanglement. The first uses a tunable coupler chain to mediate long-range correlations between distant superconducting flux qubits on the same chip, demonstrating precise control over a complex multi-element coupling network. The second moves beyond the chip: generating and characterizing large-scale microwave photonic graph states. Such states can transmit quantum information with tolerance against photon loss. Together, these demonstrations support the development of multiqubit superconducting modules, with high-fidelity interconnects between them.
