Generalized quantum XOR-gate for quantum teleportation and state purification in arbitrary dimensional Hilbert spaces

Gernot Alber, Aldo Delgado, Nicolas Gisin, Igor Jex

摘要:

本文给出了量子异或门在任意维希尔伯特空间中的推广。与单粒子傅立叶变换一起,该门能够执行各种任务,这些任务对于任意维希尔伯特空间中的量子信息处理是重要的。这些任务包括贝尔态的制备、量子隐形传态和量子态纯化。提出了一种基于非线性光学元件的广义异或门的物理实现。

英文摘要:

A generalization of the quantum XOR-gate is presented which operates in arbitrary dimensional Hilbert spaces. Together with one-particle Fourier transforms this gate is capable of performing a variety of tasks which are important for quantum information processing in arbitrary dimensional Hilbert spaces. Among these tasks are the preparation of Bell states, quantum teleportation and quantum state purification. A physical realization of this generalized XOR-gate is proposed which is based on non-linear optical elements.
