Iterative minimization algorithm on a mixture family
Masahito Hayashi
Iterative minimization algorithms appear in various areas including machine learning, neural networks, and information theory.The em algorithm is one of the famous iterative minimi…
Commitment capacity of classical-quantum channels
Masahito Hayashi, Naqueeb Ahmad Warsi
We study commitment scheme for classical-quantum channels. To accomplish this we define various notions of commitment capacity for these channels and prove matching upper and lower…
Bregman divergence based em algorithm and its application to classical and quantum rate distortion theory
Masahito Hayashi
We formulate em algorithm in the framework of Bregman divergence, which is a general problem setting of information geometry. That is, we address the minimization problem of the Br…
On the Capacity of Quantum Private Information Retrieval from MDS-Coded and Colluding Servers
Matteo Allaix, Seunghoan Song, Lukas Holzbaur +3
In quantum private information retrieval (QPIR), a user retrieves a classical file from multiple servers by downloading quantum systems without revealing the identity of the file.…
Secure list decoding and its application to bit-string commitment
Masahito Hayashi
We propose a new concept of secure list decoding, which is related to bit-string commitment. While the conventional list decoding requires that the list contains the transmitted me…
Asymptotically Secure Network Code for Active Attacks and its Application to Network Quantum Key Distribution
Masahito Hayashi, Ning Cai
When there exists a malicious attacker in the network, we need to be careful of eavesdropping and contamination. This problem is crucial for network communication when the network…
