Space communication: developing a one photon-per-bit receiver using near-noiseless phase-sensitive amplification

During space-communication researchers require high-space intersatellite data transfer connectivity for deep-space missions while monitoring Earth. The technology is fundamentally influenced by available transmission power and the aperture size of receiver sensitivity. The transition from radio-frequency links to optical links is now under consideration due to its ability to significantly reduce the channel loss caused by diffraction during communication. In a widely used approach, researchers c...
