講演概要
In this talk, we give the target Hamiltonian for realizing chiral dynamics in arbitrary N-node networks. Based on the derived Hamiltonian, we present key features of chiral state transfer in multinode spin and bosonic networks. For the realistic implementation of the required Hamiltonian, we propose a modulation scheme to generate the matched effective Floquet Hamiltonian. Furthermore, we numerically simulate the multinode chiral dynamics with realistic parameters in superconducting circuits, and the results clearly show multinode chiral state transfer. Our work provides a universal and fundamental framework for understanding chiral dynamics in multinode networks. The findings will stimulate the study of quantum state transfer, quantum routing, and nonreciprocal circulators in multinode networks.
