Approach
Candidates need to write about the quantum key distribution technology and discuss about its possible applications.
Introduction
The concept of quantum key distribution (QKD) was first proposed in the 1970s. The idea was incredibly simple yet it still took until the 1990s, when the connection was made to entanglement, that physicists started to get really interested. Since then, the progress has been remarkable and it is now perhaps the most mature quantum technology, being commercially available for over 15 years now.
Quantum key distribution technology
Quantum Key Distribution (QKD), also known as Quantum Cryptography, is a mechanism for developing secure communication. It enables the distribution and sharing of secret keys, which are necessary for cryptographic protocols. The conventional cryptosystems used for data-encryption rely on the complexity of mathematical algorithms, whereas the security offered by quantum communication is based on the laws of Physics.
Applications of quantum key distribution technology
Conclusion
The power of start-ups and Big Tech corporations involved in developing quantum technology and applications must be harnessed. The focus should be to develop an overarching strategy for the next 10-15 years. The strategy must ensure that there is no misallocation of resources and that the efforts put in are concentrated in key areas that provide both economic and strategic benefits.
