Photonic Quantum Information Technologies Explored by Quantum Optics Research

Abstract

The quantum nature of light provides us with a novel technology for information processing and communication that is based on the principle of quantum mechanics. The Optical Science Laboratory of NTT Basic Research Laboratories has been engaged in investigating photonic quantum information processing, which involves quantum cryptography and quantum computing. These Feature Articles present the current status of our research activities involving quantum optical state control and the underlying lightmatter interaction.
