Scientists hypothesis: Aliens could use quantum messages to contact us

The question of communication with any alien beings is one of the central points for those looking for life beyond the Earth. Cinema has been at the forefront on this front - just think of Dennis Villeneuve's Arrival - but the topic has also been dealt with by writers and other figures. A study of a few months ago - it was published in the journal Physical Review - also took into consideration quantum and the conclusions are interesting: certain signals could travel to interstellar distances, so it cannot be excluded that an alien civilization is already sending us messages .
