Manipulating the quantum steering direction with sequential unsharp measurements
XH Han, HC Qu, X Fan, Y Xiao, YJ Gu - Physical Review A, 2022 - APS
Quantum steering exhibits an inherent asymmetric property that differs from both quantum
entanglement and Bell nonlocality, which leads to no-way, one-way, and two-way steering …

Sequential detection of genuine multipartite entanglement is unbounded for entire hierarchy of number of qubits recycled
C Srivastava, M Pandit, U Sen - arXiv preprint arXiv:2208.08435, 2022 - arxiv.org
Experimental detection of entanglement certainly disturbs the underlying shared state. It is
possible that the entanglement content of the system is lost in the process of its detection …
