Abstract
Quantum memory provides a platform for building quantum networks in quantum information processing. Applications of said networks include quantum gates for quantum computing and quantum repeaters for long distance quantum key distribution. An optical quantum memory can be realized by a cold atom system combined with electromagnetically induced transparency (EIT). However, room temperature quantum memory via vapor cells benefit from its easy operation without the need for laser cooling and trapping, promoting the scalability. In this work, we studied and tested EIT in a Rubidium vapor cell at room temperature, by storing and retrieving a classical light source using probe and control lasers. We also constructed a portable quantum memory system and realized the storage of light at the single-photon level at room temperature. For a future perspective, we designed the quantum memory system with cavities, wishing to breakthrough in storage efficiency. | 37 pages
