Remote extraction and destruction of spread qubit information
Yoshiko Ogata, Mio Murao
Necessary and sufficient conditions for deterministic remote extraction and destruction of qubit information encoded in bipartite states using only local operations and classical c…

Local distinguishability of quantum states in infinite dimensional systems
Yoshiko Ogata
We investigate local distinguishability of quantum states by use of the convex analysis about joint numerical range of operators on a Hilbert space. We show that any two orthogonal…

Decoherence free algebra
Yoshiko Ogata
We consider the decoherence free subalgebra which satisfies the minimal condition introduced by Alicki. We show the manifest form of it and relate the subalgebra with the Kraus rep…
