FREE-SPACE QUANTUM COMMUNICATIONS IN HARSH ENVIRONMENT
Abstract
Nature does not allow us to remove quantum noise perfectly. The control of quantum noise is a main subject in quantum information science. We aim to develop sensing and communication technologies by sophisticated treatment of quantum noise control methods. Toward this, we take two different approaches; One is to reduce the effect of quantum noise for optimal detection and precision measurement using quantum interference and entanglement, and another is to enhance the effect of quantum noise for secure optical communications based on the true randomness of quantum noise. In this project, we clarify the theoretical basis for optimal control of quantum interference and entanglement and challenge to demonstrate experimentally new control methods of quantum noise toward developing future quantum sensing and communication technologies.
