Entanglement transition in unitary system-bath dynamics
Bo Xing, Giuliano Chiriacò, Paola Cappellaro +2
The evolution of a system coupled to baths is commonly described by a master equation that, in the long-time limit, yields a steady-state density matrix. However, when the same evo…
Exploring the performance of superposition of product states: from 1D to 3D quantum spin systems
Apimuk Sornsaeng, Itai Arad, Dario Poletti
Tensor networks (TNs) are one of the best available tools to study many-body quantum systems. TNs are particularly suitable for one-dimensional local Hamiltonians, while their perf…
Statistics-encoded tensor network approach in disordered quantum many-body spin chains
Hao Zhu, Ding-Zu Wang, Shi-Ju Ran +1
Simulating the dynamics of quantum many-body systems with disorder is a fundamental challenge. In this work, we propose a general approach -- the statistics-encoded tensor network…
Quantum Estimation with State Symmetry-Induced Optimal Measurements
Jia-Xuan Liu, Hai-Long Shi, Chunfeng Wu +1
A central challenge in quantum metrology is identifying optimal measurements that saturate the quantum Cramer-Rao bound under realistic constraints, e.g., local measurements. We sh…
Many-body critical non-Hermitian skin effect
Yi Qin, Yee Sin Ang, Ching Hua Lee +1
Criticality in non-Hermitian systems unveils unique phase transitions and scaling behaviors beyond Hermitian paradigms, offering new insights into the interplay between gain/loss,…
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…
