Superdense teleportation for space applications
Trent Graham, Herbert Joseph Bernstein, H. Javadi +2 more
We report the implementation of a novel entanglement-enabled quantum state communication protocol, known as SuperDense Teleportation, using photons hyperentangled in polarization and orbital angular momentum. We used these techniques to transmit unimodular ququart states between distant parties with an averaged fidelity of 86.2±3%; almost twice the classical limit of 44%. We also propose a method to use SuperDense Teleportation to communicate quantum states from a space platform, such as the International Space Station, to a terrestrial optical telescope. We evaluate several configurations and investigate the challenges arising from the movement of the space station with respect to the ground.
