This study presents a scalable protocol for high-fidelity quantum state transfer in a two-dimensional quantum network using a superconducting quantum circuit with 36 tunable qubits. The protocol leverages a general optimization procedure to overcome quantum chaotic behavior, enabling the transfer of single-qubit excitations, two-qubit entangled states, and two excitations in a network with inherent imperfections. The approach maps the quantum network to a large-spin system, allowing for efficient state transfer by synchronizing the precession of spins. The protocol is robust against defects and cross-couplings, achieving high fidelity in both single- and two-excitation transfers. The results demonstrate that the protocol can achieve high-fidelity quantum state transfer even in the presence of imperfections, with fidelities of 0.90 for single-excitation, 0.84 for Bell states, and 0.74 for two-excitation states. The study also shows that the protocol can be extended to larger networks, where quantum chaotic behavior is more pronounced, and provides insights into the role of quantum ergodicity in quantum state transfer. The results highlight the importance of optimizing inter-qubit couplings to achieve efficient quantum state transfer in quantum networks.This study presents a scalable protocol for high-fidelity quantum state transfer in a two-dimensional quantum network using a superconducting quantum circuit with 36 tunable qubits.
