Entanglement Distillation of some Rank-Five Symmetric NPT States in Two-Qutrit Systems
Yuwei Lei, Zihua Song, Lin Chen +1
Entanglement distillation is a fundamental task in quantum information processing. In this work, we investigate the distillability properties of a class of two-qutrit symmetric NPT…

High-Dimensional Carrier-Assisted Entanglement Purification Based on Mutually Unbiased Bases
Zihua Song, Lin Chen, Yongge Wang
Distilling high-dimensional entanglement under general asymmetric Pauli noise remains challenging. For the unprocessed qutrit single-carrier recurrence studied here, severe noise a…

Entanglement distillation on symmetric two-qutrit entangled states of rank five
Zihua Song, Lin Chen, Yongge Wang
Entanglement distillation is a key step in quantum information, both theoretically and practically. It has been proven that non-positive-partial transpose (NPT) entangled states of…
