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…
Observation of multiple steady states with engineered dissipation
Li Li, Tong Liu, Xue-Yi Guo +8
Simulating the dynamics of open quantum systems is essential in achieving practical quantum computation and understanding novel nonequilibrium behaviors. However, quantum simulatio…
Quantum simulation of topological zero modes on a 41-qubit superconducting processor
Yun-Hao Shi, Yu Liu, Yu-Ran Zhang +21
Quantum simulation of different exotic topological phases of quantum matter on a noisy intermediate-scale quantum (NISQ) processor is attracting growing interest. Here, we develop…
Observation of entanglement negativity transition of pseudo-random mixed states
Tong Liu, Shang Liu, Hekang Li +7
Multipartite entanglement is a key resource for quantum computation. It is expected theoretically that entanglement transition may happen for multipartite random quantum states, ho…
