Abstract:

Topological phases of matter are of both fundamental and practical interest. In this talk, we will introduce our recent progresses in exploring both equilibrium and nonequilibrium higher-order topological phases using a two-dimensional programmable superconducting quantum processor. Quantum programming of nonequilibrium higher-order topological phases was experimentally achieved by constructing quantum circuits comprising >50 cycles of Floquet operators. Additionally, we introduce a universal approach based on measuring the dynamics of chiral density to identify distinct nonequilibrium higher-order topological features, including Floquet corner topological invariants and π-energy topological corner modes. Our work may enable the use of programmable quantum processors to explore exotic higher-order nonequilibrium topological phases of matter.
