Entanglement measures for detectability
Masahito Hayashi, Yuki Ito
We propose new entanglement measures as the detection performance based on the hypothesis testing setting. We clarify how our measures work for detecting an entangled state by exte…
Asymmetry activation and its relation to coherence under permutation operation
Masahito Hayashi
A Dicke state and its decohered state are invariant for permutation. However, when another qubits state to each of them is attached, the whole state is not invariant for permutatio…
Secure network coding with adaptive and active attack
Masahito Hayashi
Ning Cai and the author jointly studied secure network codes over adaptive and active attacks, which were rarely studied until these seminal papers. This paper reviews the result f…
Covert communication with Gaussian noise: from random access channel to point-to-point channel
Masahito Hayashi, Angeles Vazquez-Castro
We propose a covert communication protocol for the spread-spectrum multiple random access with additive white Gaussian noise (AWGN) channel. No existing paper has studied covert co…
Non-Adaptive Coding for Two-Way Wiretap Channel with or without Cost Constraints
Masahito Hayashi, Yanling Chen
This paper studies the secrecy results for the two-way wiretap channel (TW-WC) with an external eavesdropper under a strong secrecy metric. Employing non-adaptive coding, we analyz…
