Entanglement is better teleported than transmitted
Koji Yamaguchi, Achim Kempf
We show that, for the purpose of quantum communication via a quantum field, it is essential to view the field not only as a medium for transmission but also as a source of entangle…

Smooth Metric Adjusted Skew Information Rates
Koji Yamaguchi, Hiroyasu Tajima
Metric adjusted skew information, induced from quantum Fisher information, is a well-known family of resource measures in the resource theory of asymmetry. However, its asymptotic…

Beyond i.i.d. in the Resource Theory of Asymmetry: An Information-Spectrum Approach for Quantum Fisher Information
Koji Yamaguchi, Hiroyasu Tajima
Energetic coherence is indispensable for various operations, including precise measurement of time and acceleration of quantum manipulations. Since energetic coherence is fragile,…
