Here’s why quantum computing is a cat among the pigeons
Here’s why quantum computing is a cat among the pigeons Much is made of the virtues of this new technology called ‘quantum computing’, which earned itself a special mention and money allocation in Finance Minister Nirmala Sitaraman’s budget speech of February. Quantum computers, (fundamentally and not incrementally) different from conventional computers in the core of their working, will be far, far faster than the most complex (exoscale) conventional computers of today. Good, right? Not quite. The reason is, quantum computers can pose a grave threat to data security, which has implications not just in privacy and business, but also in defence and national security. Data security today is ensured by encrypting data—sort of jumbling everything up—which can be reversed only at the other end. But even computers, while encrypting data, follow certain patterns – only these patterns are so complex that to copy them would take much more computing power than is available today. That is w...
