Approach of large satellites networks communications based on quantum transmissions

At first sight, quantum key distribution (QKD) through the atmosphere (“free space”), might appear to be a very much more challenging problem than QKD with weak laser pulses in optical fiber: the transmitter and receiver must reliably acquire, point, and track each other to establish and maintain the quantum channel. We report approach development of a quantum cryptographic networks for secure space communication, including a Quantum photon source and a pulse laser source. Through that can be used to encrypt classical message, it will allow the development of global communication with unprecedented security. The essential work carried in our research paper concerns a new idea in satellites transmission whit implement of Quantum Key Distribution (QKD) algorithm based on photon encrypted code, including to reduce the telecommunication interruption risks and this will provide indeed a better free space communication quality.
