Quantum Imaging with Multiphotons and Light-matter Interaction

Quantum entanglement has recently attracted much§attention because its unique properties provide novel§applications, such as quantum computing and imaging, §beyond conventional techniques. To realize these §advancements, one has to have a reliable§entanglement-generation source, master its physical§properties, and understand light-matter interaction.§This book aims at addressing such issues.§§Untilizing momentum-momentum correlation of §biphotons, quantum imaging was initiated with §photons created from spontaneous parametric down-§conversion (SPDC). In this book, an alternative §biphoton source - Raman-EIT (electromagnetically §induced transparency) generator is introduced. The §application in imaging is considered.§§To gain further insights into quantum imaging and §lithography, we extend imaging with multiphoton §entanglement. Specifically triphoton imaging with a §W state is studied in details.§§To perform quantum computing and communication §protocols, one key element is quantum memory. In §this book, the feasibility of such a memory with use §of nonclassical SPDC light in an EIT system is §analyzed at the single-photon level.
