Creating an Uncrackable Code
During World War II, the Nazis transmitted thousands of messages a day enciphered by a machine called Enigma. The Enigma code, they believed, was unbreakable.
Then, visionary mathematician Alan Turing and a team of British cryptographers cracked the code.
Today, MIT Professor Seth Lloyd has proposed a quantum enigma machine — constructed using the principles of quantum mechanics — that is uncrackable.
