Quantum Zeno Dynamics of a Rydberg atom
QZD allows one to tailor dynamically at will a system's Hilbert space. Recent proposals, particularly in the Cavity Quantum Electrodynamics (CQED) context, highlight the interest of QZD for quantum state engineering tasks. In this talk I will report the observation of QZD in the 51-dimension Hilbert space of a large angular momentum J = 25. Continuous selective interrogation limits the evolution of this angular momentum to an adjustable multi-dimensional subspace. This confined dynamics leads to the production of non-classical 'Schrödinger cat' states, quantum superposition of angular momentums pointing in different directions.
