Optimal Visible Compression Rate For Mixed States Is Determined By Entanglement Of Purification
Masahito Hayashi
Entanglement of purification was introduced by Terhal et al. for characterizing the bound of the generation of correlated states from maximally entangled states with sublinear size…
Characterization of several kinds of quantum analogues of relative entropy
Masahito Hayashi
Quantum relative entropy $D(ρ\|σ)\defeq\Tr ρ(\log ρ- \log σ)$ plays an important role in quantum information and related fields. However, there are many quantum analogues of relati…
Local copying and local discrimination as a study for non-locality of a set
Masaki Owari, Masahito Hayashi
We focus on the non-locality concerning local copying and local discrimination, especially for a set of orthogonal maximally entangled states in prime dimensional systems, as a stu…
Universal entanglement concentration
Keiji Matsumoto, Masahito Hayashi
We propose a new protocol of \textit{universal} entanglement concentration, which converts many copies of an \textit{unknown} pure state to an \textit{% exact} maximally entangled…
Bounds on Multipartite Entangled Orthogonal State Discrimination Using Local Operations and Classical Communication
M. Hayashi, D. Markham, M. Murao +2
We show that entanglement guarantees difficulty in the discrimination of orthogonal multipartite states locally. The number of pure states that can be discriminated by local operat…
A study of LOCC-detection of a maximally entangled state using hypothesis testing
Masahito Hayashi, Keiji Matsumoto, Yoshiyuki Tsuda
We study how well answer to the question ``Is the given quantum state equal to a certain maximally entangled state?'' using LOCC, in the context of hypothesis testing. Under severa…
Second order asymptotics in fixed-length source coding and intrinsic randomness
Masahito Hayashi
Second order asymptotics of fixed-length source coding and intrinsic randomness is discussed with a constant error constraint. There was a difference between optimal rates of fixed…
General non-asymptotic and asymptotic formulas in channel resolvability and identification capacity and their application to wire-tap channel
Masahito Hayashi
Several non-asymptotic formulas are established in channel resolvability and identification capacity, and they are applied to wire-tap channel. By using these formulas, the cap…
