Maximal quantum leakage: operational interpretation and quantum channel analysis
Shuixin Xiao, Zijia Zhao, Jingge Zhu +1
Maximal quantum leakage quantifies privacy against adversaries with arbitrary intentions. In this work, we prove that computing this leakage is equivalent to minimum-error quantum…
Perturbation Analysis of Maximal Quantum Leakage
Zijia Zhao, Shuixin Xiao, Farhad Farokhi
The paper studies how the maximal quantum leakage measure changes when the quantum encoding of classical data is perturbed, providing continuity bounds and conditions based on fide…
Estimation of a sparse multi-qubit Hamiltonian via compressed sensing
Juntao Tu, Yuanlong Wang, Shuming Cheng +2
Hamiltonian estimation is an effective approach in studying the structure and dynamical evolution of quantum systems. The difficulty in estimating the Hamiltonian is that an -qu…
An Information-Theoretic Principle for Optimal Quantum Encoding: Tight Frames and Equiangular Ensembles
Farhad Farokhi, Shuixin Xiao
Optimal encoding of classical data for quantum-assisted statistical inference is investigated from an information-theoretic perspective. We prove that the accuracy of any quantum-c…
A two-disk approach to the synthesis of coherent passive equalizers for linear quantum systems
Valery Ugrinovskii, Shuixin Xiao
The coherent equalization problem consists in designing a quantum system acting as a mean-square near-optimal filter for a given quantum communication channel. The paper develops a…
Robustness analysis in static and dynamic quantum state tomography
Alan Chen, Shuixin Xiao, Hailan Ma +1
Quantum state tomography is a core task in quantum system identification. Real experimental conditions often deviate from nominal designs, introducing errors in both the measuremen…
