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…
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…
Precision and Privacy in Distributed Quantum Sensing: A Quantum Fisher Information Duality
Farhad Farokhi
We establish a quantum Fisher information (QFI) duality for distributed quantum sensor networks with local phase encoding. For any -qubit probe state, where denotes the numb…
Generalized collective quantum tomography: algorithm design, optimization, and validation
Shuixin Xiao, Yuanlong Wang, Zhibo Hou +6
Quantum tomography is a fundamental technique for characterizing, benchmarking, and verifying quantum states and devices. It plays a crucial role in advancing quantum technologies…
A DPI-PAC-Bayesian Framework for Generalization Bounds
Muhan Guan, Farhad Farokhi, Jingge Zhu
We develop a unified Data Processing Inequality PAC-Bayesian framework -- abbreviated DPI-PAC-Bayesian -- for deriving generalization error bounds in the supervised learning settin…
