Encryption and Quantum Computing

This week researchers at MIT and the University of Innsbruck announced that they have designed and built the world’s very first scalable quantum computer. With this one leap forward in technology they have essentially proclaimed as well that all existing approaches to security inherent to encryption today is now effectively obsolete. This was achieved by using five atoms in an ion trap. If you don’t understand how this works, don’t worry you can count the people who actually do in the world on your fingers and toes.

They were able to use a laser pule to transfer out an algorithm which was first concieved of in 1994 at where other than MIT by professor of computer science Peter Shor. On each atom to correctly factor the number 15. killian court

The system is also designed to allows atoms and additional lasers to be added to factor much much larger numbers creating the first system that can scale shor’s algorithm.

The algorithm is the most complicated quantum algorithm known to man kind, but it can be improved upon in a laboratory setting which is pretty remarkable. this is according to Isaac Chuang who is professor of physics, electrical engineering and computer science at MIT.

Chuang who is considered an absolute giant and trailblazer within the field of computer science and electrical engineering designed a computer in 2001 working on the model of a single molecule that could be help in superposition, which was also able to be and manipulated through nuclear magnetic resources to factor the number 15. this however was done and primarily seen as something theoretical at the time.

this is itself an entirely new math. If we understand traditional computing to operate within the perameters of the mutually exclusionary model of 0 or 1 than quantum computing needs to be understood as operating with qubits where are atomic-scale units that can be both 0 and 1 simultaneously, or neither. this state is refereed to as super position. juniper2

one of the researchers explains 3DES — pronounced trip-DES — is a mode of the DES encryption algorithm that encrypts data three times. Three 64-bit keys are used, instead of one, for an overall key length of 192 bits. The first encryption is encrypted with a second key, and the resulting cipher text is again encrypted with a third key,” Pate explained.

They go on to explain, “The implications here are twofold,” he told TechNewsWorld. “First, this development suggests that quantum computing is becoming a question of scale rather than theory, much as the development of smaller chip sizes allow for increased complexity in traditional computing.”

“The technology to maintain a 5-qubit computer is very complex and difficult,” he told TechNewsWorld, noting that it involves supercooling and laser entrapment. “These are not likely to become desktop components any time soon. In fact, the very act of using a qubit destroys it, so a 5-qubit computer is good for one solution before it has to be rebuilt.”

“While we still have a few years before quantum computers become mainstream,” Eli Dourado, director of the Technology Policy Program at the Mercatus Center at George Mason University, told TechNewsWorld, “governments and a few other security-conscious organizations should start using quantum-safe encryption techniques now.”
