Quantum Cryptography Breakthrough
Austrian physicists announced a breakthrough in the transmission of quantum cryptography messages. They have devised a method that will may allow for the messages to be bounced off of satellites as a means of transmission which removes the current limitation of using only optical fiber for transmission. Quantum cryptography uses light particles to transmit the message which allow for users to detect tampering or eavesdropping on their messages. This property comes from quantum indeterminacy (similar to Heisenberg’s uncertainty principle) which says that measuring or looking at the light particle will cause it to change its state and that leaves evidence that someone either looked at or tried to change the message.
