Quantum Entanglement Dynamics in Low-Dimensional Photonic Structures: An Empirical Study of Entangled State Manipulation

Abstract

This study investigates the dynamics of quantum entanglement in low-dimensional photonic structures, addressing a critical gap in the understanding of entangled state manipulation. Utilizing advanced photonic crystal waveguides, we conduct empirical experiments to explore the entanglement generation and evolution under varying environmental conditions. Employing a combination of quantum state tomography and single-photon interference techniques, we quantify the performance parameters of entangled states, including fidelity and coherence time. Our results reveal that specific design parameters significantly enhance the entanglement properties, achieving a fidelity of 95% in optimized structures. This work not only deepens the theoretical understanding of entanglement dynamics but also proposes practical design guidelines for future quantum technologies, emphasizing the importance of material selection and structural integrity in the development of quantum photonic devices.
