Entanglement Preserving in Quantum Copying of Three-qubit Entangled State
Zhao-Yang Tong, Le-Man Kuang
We study the degree to which quantum entanglement survives when a three-qubit entangled state is copied by using local and non-local processes, respectively, and investigate iterat…

Broadcasting of entanglement in three-particle GHZ state via quantum copying
Zhao-Yang Tong, Le-Man Kuang
We introduce entanglement measures to describe entanglement in a three-particle system and apply it to studying broadcasting of entanglement in three-particle GHZ state. We show th…

Nonlinear Decoherence in Quantum State Preparation of a Trapped Ion
Le-Man Kuang, Hao-Sheng Zeng, Zhao-Yang Tong
We present a nonlinear decoherence model which models decoherence effect caused by various decohereing sources in a quantum system through a nonlinear coupling between the system a…
