Polarization entangled photon pair source for space-based quantum communication, Phase I

Completed Technology Project

Project Introduction

The overall goal of this NASA effort is to develop and deliver efficient, single-pass quantum optical waveguide sources generating high purity hyper-entangled photon pairs for use in high-rate long-distance links. The new devices will produce hyper-entangled photon pairs with high efficiency, pure spectral properties, and low attenuation, providing the key technology required for deployment of ground-to-space links and future construction of a global quantum network. The waveguide-based technology is compact, robust, and power efficient for deployment on space-based platforms such as the International Space Station. More »
