About Our Laboratory

Introduction

 We are investigating communications technology of the future, so-called quantum info-communications, which directly controls the quantum mechanical properties of photons and electrons. The world of quantum mechanics promises a number of significant advances that are beyond the capabilities of conventional info-communications technologies. For example, it is possible to increase the reliability of information transmitted even at single-photon level by using a coding scheme that controls the quantum states of light. We aim at exploring theories to treat information in quantum mechanics properly, to develop basic technologies for controlling the quantum states of photons, and to realize as many dreams as possible for our future society.
