Quantum Information and Computation with Rydberg Atoms

Highly excited Rydberg atoms are providing strong and controllable atomic interactions ideal for quantum technology with neutral atoms and photons. In this review article, the significant properties of Rydberg atoms and their scaling with principal numbers are discussed in detail. In addition, the application of laser-excited Rydberg atoms in neutral atom quantum computation is reviewed. This review article discusses, also, the application of Rydberg polaritons in quantum optics devices including single-photon sources, photonic gates, and transistors.
