Atoms excited to Rydberg states with high principal quantum numbers have exaggerated properties such as strong dipole-dipole interaction, large values of polarizability and longer lifetimes. These exotic characteristics and a high degree of controllability make ultra-cold Rydberg atoms versatile atomic building blocks for a variety of quantum technologies such as scalable quantum information networks, precision electrometry as well as single-photon sources for secure quantum communications.
In this talk, I will give an overview of Quantum Technologies with Rydberg atoms, summarise recent results from our Rydberg experiment at RRI and give future perspectives on Quantum Simulation and Quantum Sensing with ultra-cold Rydberg atoms.
