As we know, quantum computing has capabilities beyond the reach of traditional computers. It will enable us to navigate the unchartered territory. It is faster than the available supercomputers in number crunching.
Quantum computing deserves to be mainstream. However, there are serious cybersecurity issues while deploying it. These affect banking, military, power grids, government systems and more.
The backbone of cybersecurity are cryptography and encryption. The existing encryption algorithms cannot withstand an assault of a quantum computer. It could break encryption algorithms in the financial systems.
It is believed that the quantum threat is not imminent, as such computers have not yet been deployed. However, the possibility of quantum computing being used is within sight. Cybersecurity must be upgraded and innovated to take care of the quantum scenarios.
There is a race for quantum supremacy. The US has released National Security Memorandum spelling out policies and initiatives to maintain the competitive edge in quantum computing. It aims to achieve quantum-resistant cryptography.
India has initiated National Quantum Mission (NQM) to boost R&D and take lead in quantum technology.
