Tetrapartite entanglement features of W-Class state in uniform acceleration
Qian Dong, Ariadna J. Torres-Arenas, Guo-Hua Sun +1
Using the single-mode approximation, we first calculate entanglement measures such as negativity ( and tangles) and von Neumann entropy for a tetrapartite W-Class system…

Tetrapartite entanglement measures of W-Class in noninertial frames
Ariadna J. Torres-Arenas, Edgar O. Lopez-Zuniga, J. Antonio Saldana-Herrera +3
We present the entanglement measures of a tetrapartite W-Class entangled system in noninertial frame, where the transformation between Minkowski and Rindler coordinates is applied.…
