This type of communication leverages the unique properties of quantum mechanics, such as entanglement and superposition, to transmit information. One of the main promises of quantum communication is the ability to create secure and indestructible communication links, which do not require a line of sight to function. Moreover, quantum communication is theoretically immune to interceptions, making it ideal for secure transmissions.

Quantum communication could therefore solve an important problem in the space context: the need for transmission and reception means to “see” each other physically. With quantum communication, it could be possible to send signals over great distances in space without the need for a direct line of sight.
