Quantum physics

Calculations indicate that aliens could broadcast quantum communications to Earth.

According to a new study, quantum transmissions could travel across interplanetary distances. An intelligent alien civilization could beam quantum messages to Earth. Particles of light, or photons, could be transmitted over vast, interstellar distances without losing their quantum nature, researchers report June 28 in Physical Review D. That means scientists searching for extraterrestrial signals could also look for quantum messages
