Dissipative preparation of Laughlin-like states
Tong Liu
Fractional quantum Hall (FQH) states are a central paradigm of strongly correlated quantum matter and a key platform for topological quantum computation. Here, we propose a purely…
Topological eigenvalues braiding and quantum state transfer near a third-order exceptional point
He Zhang, Tong Liu, Zhongcheng Xiang +3
Non-Hermitian systems exhibit a variety of unique features rooted in the presence of exceptional points (EP). The distinct topological structure in the proximity of an EP gives ris…
High-order topological pumping on a superconducting quantum processor
Cheng-Lin Deng, Yu Liu, Yu-Ran Zhang +21
High-order topological phases of matter refer to the systems of -dimensional bulk with the topology of -th order, exhibiting -dimensional boundary modes and can be cha…
Interplay between disorder and topology in Thouless pumping on a superconducting quantum processor
Yu Liu, Yu-Ran Zhang, Yun-Hao Shi +24
Topological phases are robust against weak perturbations, but break down when disorder becomes sufficiently strong. However, moderate disorder can also induce topologically nontriv…
