Complete Classification of Reversible Entanglement Transformations of Two Qutrits
Wei Song, Xiao-Lan Zong, Ming Yang
Suppose Alice and Bob can transform one shared mixed state into another by local operations and classical communication, and can also recover the first state from the second. What…

Five-Dimensional Compatibility and Stratified Local-Unitary Structure of Pure Three-Qubit States
Wei Song, Xiao-Lan Zong, Ming Yang
We investigates the joint compatibility problem of the three pairwise concurrences, the three-tangle, and the Kempe invariant in arbitrary pure three-qubit states, and gives necess…

Kempe-Invariant Ordering of Three-Qubit Pairwise Entanglement under Local Depolarization
Wei Song, Xiao-Lan Zong, Ming Yang
Pure three-qubit states with the same pairwise concurrences and three-tangle can still have different Kempe invariants. We show that the Kempe invariant orders the entanglement dyn…
