First there will be a discussion of quantum optics and the photon picture of light. Next, I will describe our four-wave mixing experiments in rubidium vapor cells and how we generate quantum light in the lab. The four-wave mixing process generates "twin beams" that exhibit squeezing and therefore entanglement that can be used for applications such as quantum communication and quantum imaging. Using a new technique, we recently demonstrated low frequency squeezing (< 10 Hz) which should make quantum imaging experiments feasible.
