Quantum Physics Can Keep Your Data Safe

No scientific field exists in a vacuum, and this article from Science News is a wonderful example of what can happen when something so abstract as particle physics is applied to everyday problems.

When transmitting sensitive information online, "keys" are used to make the data unintelligible for anyone lacking the proper key. Quantum entanglement allows secure data sharing by basing key sharing on transmitting particles and measuring them.

This comic perfectly illustrates my point.
