Tetrapartite entanglement features of W-Class state in uniform acceleration

2019 · Frontiers of Physics

Using the single-mode approximation, we first calculate entanglement measures such as negativity (1–3 and 1–1 tangles) and von Neumann entropy for a tetrapartite W-Class system in noninertial frame and then analyze the whole entanglement measures, …
