ISRO makes a breakthrough demonstration of free-space Quantum Key Distribution (QKD) over 300 m
On 22 March, ISRO Successfully makes a breakthrough demonstration of free-space Quantum Key Distribution (QKD) over 300 m.
- MECHANISM
Many Important and Key technology was grown to accomplish goal, which includes the use of indigenously developed NAVIC receiver for time synchronization between the transmitter.
- What Is Quantum Key Distribution?
Quantum key distribution (QKD) is a secure communication method which implements a cryptographic protocol involving components of quantum mechanics. It enables two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages.
- Experiment
This Free-Space QKD was perform at Space Application Center (SAC) in Ahmedabad, between two buildings within the ISRO capamus of 300 m.
It was Preform at night in order to conform that there is no interference of sunlight.

- USES
Its a Satellite Based Quantum Communication that ensure the unconditional data Security.The Conventional Cryptosystem work's on complex Mathamatical Algorithm wheare as Quantum Based CryptoSystem offers Security on bases of law of Physics.
This Demonstration include live videoconefrencing using quantum key encrypted System.
