Two-way classical communication remarkably improves local distinguishability
Masaki Owari, Masahito Hayashi
We analyze the difference in the local distinguishability among the following three restrictions; (i) Local operations and only one-way classical communications (one-way LOCC) are…

Local copying of orthogonal maximally entangled states and its relationship to local discrimination
Masaki Owari, Masahito Hayashi
In the quantum system, perfect copying is impossible without prior knowledge. But, perfect copying is possible, if it is known that unknown states to be copied is contained by the…

Existence of incomparable pure bipartite states in infinite dimensional systems
Masaki Owari, Keiji Matsumoto, Mio Murao
Based on set theoretic ordering properties, a general formulation for constructing a pair of convertibility monotones, which are generalizations of distillable entanglement and ent…
