Maximal entangled state

WebUnderstanding the Bloch vector representation for multi-qubit states explains why, when we try to plot a two-qubit maximally entangled state in the Bloch sphere, we get an "empty" plot. Since the reduced density matrices of a state like: $$ \psi_{AB} \rangle = \frac{1}{\sqrt{2}} ... Webquantum states for any number of parties n, such that all of their reductions to ⌊n=2⌋ parties are maximally mixed [1,2]. If this is the case, maximal entanglement is present across all bipartitions and, accordingly, these states are also known as absolutely maximally entangled (AME) states [3–18]. These states have been shown to be a ...
