We use quantum-enhanced satellites to provide quantum communication on a global scale.
Quantum Communication on a global scale
Current quantum communication technologies are limited by a fixed amount of tolerable loss for the quantum signals. In fibers, this loss scales exponentially, which makes it hard to build a global quantum communication network. In contrast, loss scales quadratically when light propagates through free space. One may capitalize on this fact by utilizing the platform of satellites to perform efficient quantum communication.
