Scientists working at Max Planck Institute have built an elementary quantum network having a pair of entangled atoms. This quantum network transmits information through single photons. The special thing about this quantum network is that it is the first of its kind. For those used to determine the accuracy of old silicon based computer chips, shifting to this rather innovative concept of computing will be a daunting task.
According to Scientific Computing, the success was hard earned and it took a team of scientists years of dedicated efforts to accomplish the mission. The main challenge before the team led by Prof. Rempe was to find out a way of ensuring full control over the components of quantum network. The network receptor node was made of two atoms and the team had to ensure that the atoms remained stationery. In case the atoms were allowed to float freely, they would not communicate with photons that were primarily responsible for relaying information between the two atoms.
Rempe seemed virtually elated with the team’s accomplishment. According to Rempe, this approach to quantum network holds great significance for the future as it offers clear perspective for scalability. A team of researchers at University of Vienna worked on quantum networking. This involved transmitting an algorithm to a computer, trying it and getting it back without the operator being able to snoop on the operation. The existence of sub atomic particles in multiple states works to the advantage of quantum networking.
The concept of quantum computing is theoretical for present with the demonstration being limited to laboratory conditions only. Bringing quantum computers into operation will take time and some more concerted efforts. The dominance of their digital counterparts seem unchallenged for the present, as cost is a big hindrance when it comes to replacing digital technology with quantum.
