Second-level termination of the PPT entanglement-cost hierarchy for two qutrits
Wei Song, Xiao-Lan Zong, Ming Yang
We prove that for arbitrary two-qutrit quantum states, the semidefinite programming lower-bound hierarchy for the PPT entanglement cost terminates at the second level. Therefore, u…
Complete Classification of Reversible Entanglement Transformations of Two Qutrits
Wei Song, Xiao-Lan Zong, Ming Yang
We study single-copy exact deterministic transformations of bipartite quantum states under local operations and classical communication (LOCC), and give a complete classification o…
Supporting functionals and singular boundary geometry of two-qubit entanglement of formation
Wei Song, Xiao-Lan Zong
We give a criterion for the existence of a global supporting affine functional for the entanglement of formation at an entangled two-qubit state. It exists if and only if the spin-…
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…
Monogamy of quantum entanglement
Xiao-Lan Zong, Hao-Hao Yin, Wei Song +1
Unlike classical correlation, quantum entanglement cannot be freely shared among many parties. This restricted shareability of entanglement among multi-party systems is known as mo…
