Single-Photon Generation, Storage, Synchronization, and Interaction in Hot Atomic Vapor

Complex quantum states of light, containing many photons entangled over many modes, are important for a variety of quantum technology applications, from demonstrations of quantum advantage, through super-sensitive metrology, to measurement-based quantum computation. The creation of such states in a scalable manner has been, and to a large extent, still is, a standing scientific and engineering challenge.
In this talk, I will present our continuing work toward the creation of such complex quantum states of light using a relatively simple and potentially scalable system: a set of atomic vapor cells at or above room temperature. I will discuss our implementations of two of the three necessary components for such a feat:  a noise-free quantum memory [1,2]  and two identical, memory-compatible single-photon sources [3]. I'll also present very recent results demonstrating active synchronization of the photon sources by using the memory. Finally, I'll discuss our path toward the third ingredient, a few-photon-level non-linear component.
