Fast topological pumping for the generation of large-scale Greenberger-Horne-Zeilinger states in a superconducting circuit
文献摘要：
Topological pumping of edge states in the finite lattice with nontrivial topological phases provides a powerful means for robust excitation trans-fer,requiring extremely slow evolution to follow an adiabatic transfer.Here,we propose fast topological pumping via edge channels to generate large-scale Greenberger-Horne-Zeilinger(GHZ)states in a topological superconducting circuit with a sped-up evolution process.The scheme indicates a conceptual way of designing fast topological pumping related to the instantaneous energy spectrum characteristics rather than relying on the shortcuts to adiabaticity.Based on fast topological pumping,large-scale GHZ states show greater robustness against on-site potential defects,the fluctuation of couplings and losses of the system in comparison with the conventional adiabatic topological pumping.With experimentally feasible qutrit-resonator coupling strengths and moderate decay rates of qutrits and resonators, fast topological pumping drastically improves the scalability of GHZ states with a high fidelity. Our work opens up prospects for the realization of large-scale GHZ states based on fast topological pumping in the superconducting quantum circuit system, which provides potential applications of topological matters in quantum information processing.
