Concurrence for a two-qubits mixed state consisting of three pure states in the framework of SU(2) coherent states

D-Concurrence Bounds for Pair Coherent States

“…Some measures such as concurrence [12,13,14,15], negativity [16,17,18], and tangle [19,20,21] can be used for quantifying entanglement. Experimental quantification of entanglement has attracted more attention recently [22,23,24,25].…”
