Geometric optimization for quantum communication
Chengkai Zhu, Hongyu Mao, Kun Fang +1
Determining the ultimate limits of quantum communication, such as the quantum capacity of a channel and the distillable entanglement of a shared state, remains a central challenge…

Towards the ultimate limits of quantum channel discrimination and quantum communication
Kun Fang, Gilad Gour, Xin Wang
Distinguishability is fundamental to information theory and extends naturally to quantum systems. While quantum state discrimination is well understood, quantum channel discriminat…
