Ever since the phenomenon of entanglement was discovered, humans have been enthralled by visions of communication at faster than the speed of light. Recent experiments with the Micius satellite (1) appear to move us closer to practical satellite based quantum communication. Bringing entanglement to applications could propel humanity to a different level.
Humans have been constrained optimizers. From inception, they have been prisoners of space and time. Their ability to physically transport their inelegant bodies has been inferior to most animals that surround them and their inability to see for half the day, made them vulnerable. Later, they will find that they cannot communicate faster than the speed of light and they cannot travel faster than a fraction of this theoretical limit. To make matters worse, they were greeted by silence in close quarters, albeit their space broadcasting and listening methods, remain embarrassingly archaic. Humans remain to be prisoners of space and time and it appears that it would be forever.
Entanglement provides a mild hope out of these hard constraints. Beating light can lift the spirits of humans and open up the universe that largely remains unapproachable.
