Robust entanglement measure for mixed quantum states
Dharmaraj Ramachandran, Aditya Dubey, Subrahmanyam S. G. Mantha +1
We introduce an entanglement measure, the Modified Bloch Norm (MBN), for finite-dimensional bipartite mixed states, based on the improved Bloch matrix criteria. MBN is demonstrated…
