Abstract

The preparation of simple entangled quantum systems and the demonstration of their non-classical properties has been a challenging goal since the early days of quantum mechanics and the famous Einstein Poldolsky Rosen (EPR) paper. Manipulation of tailored entangled states also seats at the heart of the physics of quantum information. Using "circular Rydberg atoms" strongly interacting one by one with a zero or one photon field stored in a high finesse microwave superconducting cavity, we prepare tailored entangled involving up to three qubits[1] in a controlled sequence of quantum gate operation.
