The RCA encryption uses coding and large numbers to encrypt. Traditional computers are not able to decode this as they cannot factor in big numbers. Two scientists from MIT have made the Quantum computers more of a reality. The first Quantum computer was used in 1994, but it was until 2001 when Isaac Chuang managed to do any algorithms. However, He only succeeded to factor in numbers to 15.
But he has recently gone a step further and perfected his prototype and now uses an electrical field and a laser beam to pulse out the qubits. He is much closer to making his dream a reality. But his success has raised many security fears. Data lasts a very long time. The fear is that once he or some else manage to perfect the computer, company secrets can be stolen.
"I think people are starting to get freaked out about it," said Chuang. "They still believe that it's anywhere from 15 to 30 years away, but data can last a very long time. The good news is most of the data we had doesn't have to be kept secure for 30 years, but some of it does."
But he also believes that by the time Quantum computers become a reality better encryption will be used. He looks forward to a time atom encryption will be utilized. He also thinks that the government will be upset with this as the laws of physics will be keeping people's information safe, making it tough to crack.
