Quantum Internet

 

When we are in information superhighway the big concern is how to keep our data secure.And we are almost done.Researchers have been working on quantum technology to secure internet.This upcoming technology is known as quantum key distribution or QKD.

In China and Switzerland quantum technology is used to encrypt messages as a experiment.

Using this technique the network transmit photons in specific quantum states to create a cryptographic key.Using QKD data can be encrypted over non-quantum networks due to its mathematical complexity.

In order to decrypt the messages a very powerful computer is necessary.The beauty of the QKD is that if anybody try to hack the quantum key it would alter the quantum states of the photons and alerts the users.

At present the network range is restricted  due to the issues of quantum stability over long distances but that problem can be solved with the help of quantum repeaters.
