Quantum Satellites Are a Big Step toward the Unhackable InternetIt is theoretically possible for a space satellite to send and receive entangled photons, and that may even be feasible soon.
Space-based transmission of quantum cryptographic keys could make the “unhackable” Internet a reality
Maybe someday there will even be a quantum computer router in space that can re-transmit entangled photons without collapsing the wave function.
But even if that is all achieved, it will do nothing to make the internet less hackable. The quantum key distribution is an attempt to solve a problem that is much more efficiently and securely solved by existing technologies. There is just no legitimate reason for a quantum satellite, except to show off some technology.
