A method of securely communicating between multiple quantum devices developed by researchers in the UK does not rely on assumptions, but instead it uses the quantum laws of physics to ensure security, which would need to be broken to hack the encryption. They report on a way of communicating securely between three or more quantum devices, irrespective of who built them. The method works by using the network’s structure to limit what an eavesdropper can learn. They used machine learning and causal inference to develop the test for the un-hackable communications system. This approach distributes secret keys in a way that cannot be effectively intercepted, because through quantum mechanics their secrecy can be tested and guaranteed… read more.
