For the first time in India, the Indian Space Research Organization on Monday demonstrated an experiment on quantum key sharing in a free space at a distance of 300 meters. A live-video conferencing was held at Space Application Center in Ahmedabad with quantum key encrypted signals between two line-of-sight buildings. that this experiment can form the basis of future quantum key encrypted data transmission between satellites and ground stations. This way of communication using quantum encrypted can be helpful in creating a secret message network. This encrypted signal using quantum will privatize the communication that need not be shared with anyone with full proof as the normal computers won’t be able to crack this signal. These signals are so big in number that it is highly important to crack them. In order to crack such quantum signals that are very much big in size, so the scientistsa quantum computer.
“The development of a quantum computer is still in the race and there is no one on this planet yet who have succeeded in developing the quantum computer successfully. A lot of countries are still into the race to get this compute developed on their end, but this innovation is not that easy”, said the ISRO officials. The normal computer which we use stores the data in a binary form of 0 or 1 but the quantum computers use qubits, which are either proton or electron, that can be 0, 1 or any superposition of any possible combination of 0 and 1. The ISRO is now working up faster to demonstrate the technology between two ground stations of India. Various key technologies were developed for this demonstration by the scientists which include NavIC receiver, which is used for time synchronization between Transmitter and receiver module.
