Here’s a little article on the macroscopic use of quantum mechanics.
“Physicists at the Commerce Department’s National Institute of Standards and Technology have taken a significant step toward transforming entanglement–an atomic-scale phenomenon described by Albert Einstein as ‘spooky action at a distance’–into a practical tool. They demonstrated a method for refining entangled atom pairs (a process called purification) so they can be more useful in quantum computers and communications systems, emerging technologies that exploit the unusual rules of quantum physics for pioneering applications such as ‘unbreakable’ data encryption.”
(Just for the record – the idea of the weird world of quantum physics being exploited to create otherwise unimaginable tools isn’t all that uncommon. The transistor is one such device and the modern microprocessor would be impossible without it.)
