Research Abstract

In this work we aim to temporally separate Fock states using a cold atomic ensemble in a high-finesse cavity. The separation is enabled by few-photon nonlinearity in a strongly-coupled atom-cavity system. In order to achieve this goal, we designed and built a novel high-finesse cavity as well as a transfer cavity to stabilize the main cavity. We also prepared a laser source to be used for trapping an atomic ensemble within the cavity mode. Aside from the vacuum system, we have thus mostly completed the construction of the experimental setup. In addition, we have performed a theoretical analysis of the relationship between the separation of Fock states and the time evolution of photon statistics. Such a theoretical framework is expected to enable us a detailed analysis of the experimental data.
