Hilbert space connectivity in non-Hermitian many-body systems: emergent scale-dependent amplification and constraint-induced skin localization
Zichang Hao, Wen-Tan Xue, Ching Hua Lee
Various exotic many-body phenomena such as quantum scars and fractons have been linked to Hilbert space fragmentation. In this work, we find that in non-Hermitian settings, Hilbert…
Local distinguishability of five orthogonal product states on bipartite and tripartite quantum systems
Guang-Bao Xu, Zi-Yan Hao, Hua-Kun Wang +2
Local distinguishability of orthogonal quantum states can effectively reduce the consumption of quantum resources and lower economic costs in quantum protocols. Although numerous a…
Interacting many-body non-Hermitian systems as Markov chains
Zichang Hao, Wei Jie Chan, Ching Hua Lee
Rich phenomenology emerges at the intersection of non-Hermiticity and many-body dynamics, yet physically realizable implementations remain challenging. In this work, we propose a g…
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…
