Heisenberg scaling based on population coding
Masahito Hayashi
We study Heisenberg scaling of quantum metrology in the viewpoint of population coding. Although Fisher information has been used for a figure of merit to characterize Heisenberg s…

Adaptive Coding for Two-Way Wiretap Channel under Strong Secrecy
Yanling Chen, Masahito Hayashi
This paper studies adaptive coding for the two-way wiretap channel. Especially, the strong secrecy metric is of our interest that is defined by the information leakage of transmitt…

Measuring quantum relative entropy with finite-size effect
Masahito Hayashi
We study the estimation of relative entropy when is known. We show that the Cramér-Rao type bound equals the relative varentropy. Our estimator attains the Cramér-Rao…
