Job Description:
Developing sustainable ICT and future telecommunications systems (e.g., 6G, quantum communications, AI-assisted) with a focus on resilience has become a key national priority. Congested radio spectrum and coexistence of broadband wireless systems produce interferences, increasing the risk of failure in future telecommunication infrastructure. Measuring weak signals amidst noise and interference presents a significant metrological challenge.
Recently, non-invasive Rydberg quantum sensing technology (RQST) has emerged as a promising solution, offering highly sensitive and traceable RF field measurements over a wide frequency range. While various designs have been reported, a comprehensive understanding from a metrology perspective remains limited.
This project, aligned with EPSRC priorities in digital futures and quantum technologies, aims to conduct a thorough study of RQST through both theoretical and experimental approaches. The main objectives are:
1. Study RQST to identify suitable frequency ranges and achievable sensitivities.
2. Develop a state-of-the-art Rydberg quantum sensing testbed and evaluate its measurement accuracy and sensitivity.
3. Apply RQST to resilient communications, assessing its advantages and limitations such as sensitivity, stability, and traceability in complex environments.
4. Create methodologies to characterize the performance of emerging telecommunication systems in complex electromagnetic environments using RQST.
