A group of researchers from the Department of Applied Mathematics and Theoretical Physics at the Cambridge University were recently able use quantum theory and relativity to produce a quantum cryptography system that can encode and decode data without allowing for external manipulation.

This study represents an important step towards creating a data transmission system that cannot be spied upon by people not included in the conversation. This is the first time such unconditional security of information was demonstrated anywhere in the world.

The breakthrough in quantum cryptography the team achieved signifies that data can now be encrypted and decrypted using complex algorithms, in a manner that does not allow third-parties to intercept and decode the message. In essence, the data is stored inside a quantum envelope.

“This is the first time perfectly secure bit commitment – relying on the laws of physics and nothing else – has been demonstrated,” says Cambridge expert Dr. Adrian Kent. He is the coauthor of a study detailing the breakthrough, published in the esteemed journal Physical Review Letters.
