A problem that has always plagued the internet is the privacy of data. How can you be certain that the data you are sending is not read by someone between you and the receiver.
Researchers at startup MagiQ have come up with a way to potentially solve this problem by looking to quantum physics. Called quantum cryptography, researchers have created an encryption method they are touting as virtually unbreakable.
They are applying the properties of quantum physics to create encryption keys. The Basic premise relies on the laws of small particles of light called photons. By simply observing a photon, it's properties are altered and it is never the same again. Using this fact, known as Heisenberg's Uncertainty Principle, use the state of a photon to generate an encryption key, it's easy then to determine if anyone has looked at it becuase it will have changed.
"Uncertainty is the principle we exploit," says Mike LaGasse, the vice-president of engineering of MagiQ's "It's fundamentally impossible to observe the key, because the photon can be measured once and only once. An eavesdropper can't measure it, and so can't get the key."
