Imagine making a phone call to somebody located on another planet somewhere in the furthest reaches of the Milky Way Galaxy. Well, soon there just might be a way to do that.
Scientists at the University of Edinburgh have proposed using the quantum properties of light to transmit messages through space, encoding binary code into the quantum state of photons rather than using traditional methods such as amplitude or frequency.
While these messages would not be able to travel faster than the speed of light, the distance they can travel isn’t restricted by the fundamental laws of physics. However, the implementation of this technology is constrained by our current engineering and technological capabilities, and we’re not quite there yet.
