Offer Description
Quantum metrology has yielded significant advancements in sensitivity and precision compared to traditional resources in recent years, revolutionizing specific fields. However, most of the breakthroughs rely on the interaction of no more than two particles, consequently limiting the geographic coverage of the sensors. This PhD thesis proposes a fundamental shift in perspective by envisioning the creation of a network of quantum sensors spread across mid-range distances, accompanied by the exploration of applications that harness the potential of such networks.
More precisely, the overall context of the PhD thesis is part of a comprehensive project with the following objectives: utilizing high-performance bipartite entangled states for secure sensor delegation; demonstrating that measuring a global parameter of a system (e.g., the sum, difference, or average of multiple phase values) using a high-dimensional quantum state achieves greater accuracy than probing the different sensors separately, whether they are quantum or classical; leveraging multipartite entangled states to guarantee measurement security at various points within a network; harnessing well-established telecom technology to showcase the feasibility of these tasks over deployed optical fiber networks, including a case study involving simulated seismic vibration detection.
the PhD thesis is part of a comprehensive and experimental project in collaboration with LiP6 (Laboratory of Computer Science Research at Sorbonne University), focusing on the generation, manipulation, and exploitation of multipartite entangled states. The main objective of the PhD will be to generate a qudit-type state through an appropriate experimental configuration, considering the most suitable observable (see figure for a frequency qudit). The dimension and observable of the state will be discussed, as well as the generation rate associated with realistic propagation losses within a fiber network. A laboratory experiment aimed at generating a first version of the state will also be considered. The application of this type of multimode state to quantum metrological protocols will also need to be established from a theoretical point of view.
