We study different phenomena associated with single-photon propagation in optical cavities coupled through optical fibers. We first address the issue of storing and delaying single-photon wavepackets in an array of microcavities. This has possible applications in developing reliable and efficient quantum repeaters that will be utilized \n \nin building long distance quantum networks. Second, we investigate a Hong-Ou-Mandel (HOM) type of interference between two photons that are produced in two coupled atom-cavity systems. The HOM effect in this setup can test the degree of indistinguishability between photons when they are stored inside cavities. This part of the dissertation also includes the study of entanglement between atoms, cavities and atom-cavity systems induced by the photons. Finally, we focus on single-photon interactions with a tiny movable mirror in the context of quantum optomechanics. We investigate how the mechanical motion of the mirror leaves its imprints on the optical spectrum of the photon \n \nThis dissertation includes previously published and unpublished co-authored material.

Superconducting nanowires can be used to detect single photons with very high sensitivity and speed in the near-infrared. We present recent results on single-photon detectors integrated with microcavities and waveguides for increased efficiency, and photon-number-resolving detectors based on arrays of nanowires.

We show how a single photon injected into a chain of optomechanical systems can be stored as a linear superposition over the array of mechanical resonators, hence building a single photon optomechanical memory.
