Tangent Space Excitation Ansatz for Quantum Circuits
Ji-Yao Chen, Bochen Huang, D. L. Zhou +3
Computing excitation spectra of quantum many-body systems is a promising avenue to demonstrate the practical utility of current noisy quantum devices, especially as we move toward…
Reliability Dynamics in a Two-Site Dissipative Quantum Spin Chain
Bowen Sun, D. L. Zhou
As a key index for applications of a device, the device's reliability is its ability to survive (function normally over time) under the influence of some environment. In this paper…
Insufficiency of Pure-State Ensembles in Characterizing Transformations of Entangled States under LOCC
C. L. Liu, Baoqing Sun, D. L. Zhou
The conditions for transforming pure entangled states under local operations and classical communication (LOCC) are well understood. A natural question then arises: Can we determin…
Learning Symmetric Hamiltonian
Jing Zhou, D. L. Zhou
Hamiltonian Learning is a process of recovering system Hamiltonian from measurements, which is a fundamental problem in quantum information processing. In this study, we investigat…
Quantum Topological Analysis on Digraphs
Yunpeng Zi, Muchun Yang, D. L. Zhou
Quantum algorithms for topological data analysis provide significant advantages over the best known classical algorithms. Unlike previous work on simplicial complexes built from po…
Measuring Incompatible Observables with Quantum Neural Networks
Muchun Yang, Yibin Huang, D. L. Zhou
The Heisenberg uncertainty principle imposes a fundamental restriction in quantum mechanics, stipulating that measuring one observable completely erases the information on its conj…
