Observation of flat-band skin effect
Xulong Wang, Dongyi Wang, Congwei Lu +4
Symmetry-protected ideal flat bands in one-dimensional (1D) Hermitian lattices are populated by compact localized states (CLS) - a special class of localization with wavefunctions…
Exceptional deficiency of non-Hermitian systems
Zhen Li, Xulong Wang, Rundong Cai +5
Exceptional points (EPs) are non-Hermitian singularities associated with the coalescence of individual eigenvectors accompanied by the degeneracy of their complex energies. Here, w…
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…
Quantum Simulation of Bound-State-Enhanced Quantum Metrology
Cheng-Ge Liu, Cong-Wei Lu, Na-Na Zhang +1
Quantum metrology explores quantum effects to improve the measurement accuracy of some physical quantities beyond the classical limit. However, due to the interaction between the s…
Controlled-NOT gate based on the Rydberg states of surface electrons
Jun Wang, Wan-Ting He, Cong-Wei Lu +3
Due to the long coherence time and efficient manipulation, the surface electron (SE) provides a perfect two-dimensional platform for quantum computation and quantum simulation. In…
Sudden death of entanglement with Hamiltonian ensemble assisted by auxiliary qubits
Congwei Lu, Wanting He, Jun Wang +2
In this paper, we theoretically propose a method to simulate the longitudinal relaxation of a single qubit by coupling it to an auxiliary qubit. In order to mimic the finite-temper…
Criticality-Based Quantum Metrology in the Presence of Decoherence
Wan-Ting He, Cong-Wei Lu, Yi-Xuan Yao +2
Quantum metrology aims to use quantum resources to improve the precision of measurement. Quantum criticality has been presented as a novel and efficient resource. Generally, protoc…
