Regular computers would take an "unimaginable amount of time" to break symmetric encryption, but quantum computers could do it in a fraction of the time.
Much of the currentresearch in quantum computing involves work at close to absolute zero. A simple breakthrough with an everyday material could see them work at more acceptable temperatures.
According to the Aarhus University in Denmark, humans spend 3 billion hours gaming away on smartphones and other mobile devices every week. If it is possible to tap into that calculating resource by just one percent, we would be more than a match...
