Entanglement Measures for Intermediate Separability of Quantum States
Tsubasa Ichikawa, Toshihiko Sasaki, Izumi Tsutsui
We present a family of entanglement measures R_m which act as indicators for separability of n-qubit quantum states into m subsystems for arbitrary 2 \leq m \leq n. The measure R_m…
Testing the EPR Locality using B-Mesons
Tsubasa Ichikawa, Satoshi Tamura, Izumi Tsutsui
We study the possibility of testing local realistic theory (LRT), envisioned implicitly by Einstein, Podolsky and Rosen in 1935, based on the Bell inequality for the correlations i…
Exchange Symmetry and Multipartite Entanglement
Tsubasa Ichikawa, Toshihiko Sasaki, Izumi Tsutsui +1
Entanglement of multipartite systems is studied based on exchange symmetry under the permutation group S_N. With the observation that symmetric property under the exchange of two c…
