论文摘要
在本文中，我们报告了对光子系统中量子纠缠的创建，表征和操纵的理论和实验研究。我们检查了量子纠缠的两个不同方面：在第一部分中，我们讨论了基于SPDC的极化输入光子源的制备和表征的实验方法。我们提供了一项审查研究，比较了非最大程度的纠缠两量纯状状态的不同纠缠措施，并将此分析扩展到高维系统。在第二部分中，我们研究了在存在振幅阻尼通道的情况下，两数Qubit系统的纠缠动态，并根据局部单一操作提出了一项计划，以保护纠缠不受纠缠的突然死亡。我们将逆转研究扩展到Qubit-Qutrit和Qutrit-Qutrit纠缠系统，并为更高维系统提出纠缠保护方案。
In this thesis, we report the theoretical and experimental investigations towards the creation, characterization, and manipulation of quantum entanglement in a photonic system. We examine two different aspects of quantum entanglement: In the first part, we discuss the experimental method for the preparation and characterization of SPDC-based polarization-entangled photon source. We provide a review study comparing different Entanglement Measures for non-maximally entangled two-qubit pure states and extend this analysis to higher-dimensional systems. In the second part, we study the entanglement dynamics of a two-qubit system in the presence of an Amplitude Damping Channel and present a scheme based on local unitary operations to protect entanglement from undergoing Entanglement Sudden Death. We extend the decoherence study to qubit-qutrit and qutrit-qutrit entangled systems and propose an entanglement protection scheme for the higher dimensional system.
