The 2023 Nobel Award in Chemistry was awarded for the discovery and synthesis of quantum dots. How have the developments of quantum dots affected the various sectors over the years?

Quantum dots works on the principle of entanglement and superposition. A change in quantum state of one particle with entangled with other, automatically change the other particle state. B. Relevance of quantum dots (1) [Communication] ex helps ensure and secure quick delivery of message over the technological platforms. → enable end encryption is possible → boot to satellite communication (2) [Security] helps in ensuring security of information sharing.

Can be used by government to secure and safe information dispersal. → Has prevented the cyber attacks thus promoting cyber hygiene. III [Economy] - economic data can be effectively and efficiently shared among the agencies. → help boost the knowledge economy. → Pow to data economic activities IV [Social sector] → can be used in education and health sector → can help boost inclusive development → use will connectivity.

Challenges (1) Lack of infrastructure capacities. (2) Privacy issues (eg storage of information) (3) Scientific interventions in the sector is lagging. (4) Required intervention by government is also lacking. Need is for boosting R&D expenditure and are required governmental approach.
