PhD Studentship in Long-Distance Continuous Variable Quantum Key Distribution

This PhD position at Manchester Metropolitan University focuses on advancing long-distance quantum key distribution (QKD) through the development of optical quantum repeaters. The project aims to address the current limitation of QKD links by creating theoretical models and experiment-ready frameworks for repeater-assisted architectures. The successful candidate will analyze repeater architectures, evaluate amplifier-enhanced and memory-assisted protocols, and provide design guidelines for future implementations. The work bridges theoretical quantum information science with practical hardware constraints, contributing to the development of large-scale, secure quantum networks. The project is ideal for applicants with a strong background in physics, electrical engineering, or computer science, and a passion for quantum technologies and independent research.

• Develop a generalized theoretical framework for quantum repeater architectures to enable long-distance entanglement distribution.
• Investigate and compare specific quantum key distribution protocols, focusing on amplifier-enhanced and memory-assisted approaches.
• Model realistic device imperfections, including loss, noise, and experimental constraints, to ensure theoretical models are practical.
• Provide design guidelines for future experimental implementations of quantum repeater networks, specifying hardware requirements and performance benchmarks.
• Contribute to the development of scalable quantum communication infrastructure by identifying viable pathways for secure quantum network deployment.
