UNHACKABLE INTERNET WILL BE MORE SECURE FOR WORLD

Why unhackable internet matters

The internet is increasingly vulnerable to hacking; a quantum network on the otherhand  would be unhackable and less vulnerable.

Who are the Key Players in this field of work

Delft University of Technology, Quantum Internet Alliance, University of Science and Technology of China

Availability of technology

Technology not available till date but would be in next decade and so

Recent research on Unhackable Internet:

During a research this year, Dutch researchers will complete a quantum internet between Delft and the Hague.

An internet based on quantum physics will soon enable inherently secure communication. A team led by Stephanie Wehner, at Delft University of Technology, is building a network connecting four cities in the Netherlands entirely by means of quantum technology. Messages sent over this network will be unhackable.

Chinese technology in this matter:

In the last few years, scientists have learned to transmit pairs of photons across fiber-optic cables in a way that absolutely protects the information encoded in them.

Recently a team in China used a form of the technology to construct a 2,000-kilometer network backbone between Beijing and Shanghai—but that project relies partly on classical components that periodically break the quantum link before establishing a new one, introducing the risk of hacking.

Delft university technology on this matter:

On the other hand, Delft network will be the first to transmit information between cities using quantum techniques from end to end.

The technology used for this purpose is called entanglement. It relies on a quantum behavior of atomic particles. The science behind is that Entangled photons can’t be covertly read without disrupting their content.

But entangled particles are difficult to create, and harder still to transmit over long distances. 

Wehner’s team has demonstrated it can send them more than 1.5 kilometers (0.93 miles), and they are confident they can set up a quantum link between Delft and the Hague by around the end of this year. Ensuring an unbroken connection over greater distances will require quantum repeaters that extend the network’s capacity of transmission.

The repeaters which will work as network extenders are currently in design at Delft. The first one might be should be completed in the next five years time , says Wehner, with a global quantum network following by the end of the decade.
