Detecting genuine multipartite entanglement by eternal non-Markovianity.
Ankit Vaishy, Subhadip Mitra, Samyadeb Bhattacharya
We devise a novel protocol to detect genuinely multipartite entangled states by harnessing quantum non-Markovian operations. We utilize a particular type of non-Markovianity known as the eternal non-Markovianity to construct a non-complete positive map to filter out the bi-separable states and detect genuine multipartite entanglement. We further propose a dynamical procedure to detect genuinely multipartite entangled states in real-time based on this theory. Our study sheds light on a hitherto unexplored connection between entanglement theory and quantum non-Markovianity.
