‘Imagine a form of encrypted communication so secure that it’s physically impossible to access it unless you’re actually at the location where you’re supposed to hear it. Quantum mechanics makes location-based cryptography possible – without any pesky codes or keys.

The basic idea is simple – create an encrypted communication where your actual physical location is the only key required to gain access to the hidden information. It would eliminate any need to create and store decryption keys, which is disproportionately the most complex and time-intensive task in cryptography. You could encrypt a secure line so that the only people who could ever hear would have to be at, say, two secure military bases, eliminating any chance of someone listening in from a third location.’
