Efficient Verification of Entangled Measurements with Local States
Kun Wang, Masahito Hayashi
We develop a framework for quantum measurement verification (QMV) using only local state preparations. For locally transitive and irreducible projective measurements, we prove that…

Characterization-free classification and identification of the environment between two quantum players
Masahito Hayashi, Longyang Cao, Baichu Yu +1
Classifying the causal structure of quantum channels is essential for verifying quantum networks and certifying quantum resources. We introduce a characterization-free protocol ena…

Generalized Quantum Stein's Lemma for Classical-Quantum Dynamical Resources
Masahito Hayashi, Hayata Yamasaki
Channel conversion constitutes a pivotal paradigm in information theory and its applications to quantum physics, providing a unified problem setting that encompasses celebrated res…
