The technologies used for communication are being updated and made better after each decade .There are various causes which demand for the updation of these technologies and one of the most important causes is the Information Security. Nowadays even the common man demands privacy while using any channel for his communication, then imagine a field where the security of information plays a crucial role such as defense, high fund transactions, and the government’s plan of action. As things become more digitized and usage of the internet increases, the requirement of data and information security also increases.
SYSTEMS AT PRESENT:
At present the most common security system is Encryption and Decryption, it is the same technology (end to end encryption) used by WhatsApp which has 2 billion active users at present. It’s not easy for even an experienced coder to break this tech but still the system is not bulletproof, there could be the possibility of a decryption tool or malware attack. Likewise in the defense sector if an army man got stuck in the enemy zone and shared the radio frequency used for communication between the troops due to an irresistible situation then this would become an enormous threat for the military troops who went for an operation.
QUANTUM REALM :
To rectify all these issues in the field of communication the researchers across the world are developing a whooping technology called Quantum communication, where they use a scientific phenomenon as a protecting tool for information. It uses some complex Quantum phenomenon called Entanglement. The speciality of this system is that no matter what’s the distance between two photons the state of one could be able to affect the other. Also Check: Freshwater fishes help find Gold
Currently countries like the US, Japan, China and several European countries are developing this technology. The country which has greater interest and focus in this technology is China, which has already sent a Quantum space satellite called as ‘Micius’ for technology demonstration with the project duration of 2 years. ISRO on the other hand has tested Quantum key distribution at 300m atmospheric channel, between the two buildings. The test includes secure texting, secure two-way video calling, image transmission. It also assured that India would make a significant step towards Satellite based Quantum Communication (SBQC) like China. By that experiment India has also proved that it could revolutionize the field of communication.

Though Quantum communication is going to be a breakthrough it has a lot of challenges in practical implementation.

HIGHLY EXPENSIVE :
This technology is not budget friendly since it’s new to the world it requires more cost optimization and proper engineering. The cost of research is also very high. Due to this, it would be hard for developing countries like India to improvise this system since the funding for these experiments from the government is very low.
LOW SCALABILITY:
Bringing this system to the group of people in an organisation is going to be a tough deal since the system is highly complicated to be handled or maintained, giving rise to low scalability of this technology.
PERFORMANCE:
The SBQC of China could transfer information which is a few bits of size, but today in the 5G era we are instantly transferring data in gigabytes (8 billion bits). As well as the robustness of these quantum signals are pretty low compared to infrared and radio wave signals which are currently in use. The entangled photon could easily lose its energy in the medium so the ideas are being used to use some channels similar to fiber optics for transferring the information.
