"Cavity quantum electrodynamics (QED) is the branch of physics which involves resonantly confining light to small volume, high-quality resonators, thereby enhancing the electric field associated with even a single photon to a level that enables coherent interactions with material systems such as single atoms. The primary goal is forming a link between ""flying Qubits"", namely photons, to ""stationary Qubits"" such as single atoms, which can perform the nonlinear interactions required for quantum computing and function as quantum memory. I suggest harnessing the most recent and advanced cavity QED capabilities with chip-based micro-cavities to achieve atom-mediated nonlinear photon-photon interactions, such as single-photon switches, quantum non-demolition measurement (QND) of photons and quantum gates. Such interactions allow the study and generation of non-classical states, and are a long sought-for technological goal in itself."
