Approximate majorization and high-order capacity of quantum depolarizing channels
Zhiwei Song, Xin Wang, Marco Tomamichel +1
A central challenge in quantum information theory is to determine whether entanglement provides an advantage for information processing when coherent operations across multiple cha…
