Arithmetic Progressions in the Graphs of Slightly Curved Sequences
Kota Saito, Yuuya Yoshida
A strictly increasing sequence of positive integers is called a slightly curved sequence with small error if the sequence can be well-approximated by a function whose second deriva…
Optimal Mechanism for Randomized Responses under Universally Composable Security Measure
Yuuya Yoshida, Man-Hong Yung, Masahito Hayashi
We consider a problem of analyzing a global property of private data through randomized responses subject to a certain rule, where private data are used for another cryptographic p…
Asymptotic and Non-Asymptotic Analysis for Hidden Markovian Process with Quantum Hidden System
Masahito Hayashi, Yuuya Yoshida
We focus on a data sequence produced by repetitive quantum measurement on an internal hidden quantum system, and call it a hidden Markovian process. Using a quantum version of the…
Asymptotic Properties for Markovian Dynamics in Quantum Theory and General Probabilistic Theories
Yuuya Yoshida, Masahito Hayashi
We address asymptotic decoupling in the context of Markovian quantum dynamics. Asymptotic decoupling is an asymptotic property on a bipartite quantum system, and asserts that the c…
