Sample Complexity of Locally Differentially Private Quantum Hypothesis Testing

Hao-Chung Cheng, Christoph Hirche, Cambyse RouzÃ©

Quantum state discrimination is an important problem in many information processing tasks. In this work we are concerned with finding its best possible sample complexity when the s…

Maximal $I^\pm$ -Leakage for Quantum Privacy Mechanisms

Bo-Yu Yang, Hsuan Yu, Hao-Chung Cheng

In this work, maximal $I^\pm$ -leakage is introduced to quantify how much a quantum adversary can learn about any sensitive information of data upon observing its disturbed version via…
