Researchers at New Mexico's Los Alamos National Labs have revealed that they have been running a so-called quantum Internet for the last two and a half years.

Quantum Internet is reportedly a form of Internet or communication that theoretically can not be hacked. Quantum cryptography industry will thus open opportunities to fully secure and reliable Internet connections.

As per Heisenberg's Uncertainty Principle, in case you observe some sub-atomic particles, such as photons, you can change them. Thus, if you send a message using photons, the message or information would change the very moment anyone tried to see it.

MIT Technology reported that the act of retransmitting such an encoded message or information meant reading it, and thus changing it. Folks at Los Alamos National Labs tried to create a hub and spoke-type network, where all messages or information get routed from a mid point where the information is altered to conventional classical bits and subsequently altered again into quantum bits to be sent towards the recipient.

Swiss firm ID Quantique, which was founded in the year 2001, is already working to offer quantum secured messages. The project has already raised one million euros to fund the work.

Researchers are highlighting some possible applications for Quantum internet, including cryptography for the smart grid and as a retrofit solution to existing infrastructures of communications.

Quantum secure Internet, at the moment, has still a long way to become commercially viable as scalability issues are still arising from the difficulty of processing very high numbers of links at the hub.
