Topological phases are robust against weak perturbations, but break down when disorder becomes sufficiently strong. However, moderate disorder can also induce topologically nontrivial phases. Thouless pumping, as a (1+1)D counterpart of the integer quantum Hall effect, is one of the simplest manifestations of topology.

- High-order topological phases involve systems with unique multi-dimensional properties, showing localized states on lower-dimensional boundaries and can be used in topological pumping experiments.
- The research demonstrates the creation of corner-localized states on a lattice of superconducting qubits using a process that modifies quantum interactions adiabatically.
- The team also examines how these topological pumps handle different types of disorder, providing insights into their stability and encouraging further exploration of high-order topological phases in quantum systems.
