A note about quantum cryptography

It is based on physics, which helps to acquire the output by using the existing knowledge of physics.it is also known as quantum encryption. by using the principles of quantum mechanics, it helps to protect the message and encrypt them in a way so that no one besides the receiver can read it.it has always played a pivotal role for large companies and government. For example, if someone tries to read the data which is encoded, the state of quantum will be changed immediately.

 its most widely used application is QDK (quantum key distribution). By using quantum communication, establishes a shared key for two parties without the interference of the third party.
