A Recursive Module-Coupling Algorithm for Computing Low-Energy Eigenstates
Dihang Sun, Nannan Ma, Ching Hua Lee +2
Finding the eigenstates of a many-body Hamiltonian is a fundamental challenge in physics and computational science. Since the search space grows exponentially with system size, num…
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…
Benchmarking Quantum Solvers in Noisy Digital Simulations for Financial Portfolio Optimization
Ruizhe Shen, Zichang Hao, Ching Hua Lee
In this work, we benchmark two prominent quantum algorithms: Quantum Imaginary-Time Evolution (QITE) and the Quantum Approximate Optimization Algorithm (QAOA) for obtaining the gro…
Interacting non-Hermitian edge and cluster bursts on a digital quantum processor
Jin Ming Koh, Wen-Tan Xue, Tommy Tai +2
A lossy quantum system harboring the non-Hermitian skin effect can in certain conditions exhibit anomalously high loss at the boundaries of the system compared to the bulk, a pheno…
Topologically protected negative entanglement
Wen-Tan Xue, Ching Hua Lee
The entanglement entropy encodes fundamental characteristics of quantum many-body systems, and is particularly subtle in non-Hermitian settings where eigenstates generically become…
Experimental observation of exceptional bound states in a classical circuit network
Deyuan Zou, Tian Chen, Haiyu Meng +3
Exceptional bound (EB) states represent an unique new class of robust bound states protected by the defectiveness of non-Hermitian exceptional points. Conceptually distinct from th…
