Secure Network Code for Adaptive and Active Attacks with No-Randomness in Intermediate Nodes
Ning Cai, Masahito Hayashi
In secure network coding, there is a possibility that the eavesdropper can improve her performance when she changes (contaminates) the information on the attacked edges (active att…
Role of Hypothesis Testing in Quantum Information
Masahito Hayashi
Recently, it is well recognized that hypothesis testing has deep relations with other topics in quantum information theory as well as in classical information theory. These relatio…
Universally Fisher-Symmetric Informationally Complete Measurements
Huangjun Zhu, Masahito Hayashi
A quantum measurement is Fisher symmetric if it provides uniform and maximal information on all parameters that characterize the quantum state of interest. Using (complex projectiv…
Secure uniform random number extraction via incoherent strategies
Masahito Hayashi, Huangjun Zhu
To guarantee the security of uniform random numbers generated by a quantum random number generator, we study secure extraction of uniform random numbers when the environment of a g…
Coherence and entanglement measures based on Rényi relative entropies
Huangjun Zhu, Masahito Hayashi, Lin Chen
We study systematically resource measures of coherence and entanglement based on Rényi relative entropies, which include the logarithmic robustness of coherence, geometric coherenc…
Secure Quantum Network Coding on Butterfly Network
Masaki Owari, Go Kato, Masahito Hayashi
Quantum network coding on the butterfly network has been studied as a typical example of quantum multiple cast network. We propose secure quantum network coding on the butterfly ne…
