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…

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…
