Detailed explanation-1: -Quantum computers are exceedingly difficult to engineer, build and program. As a result, they are crippled by errors in the form of noise, faults and loss of quantum coherence, which is crucial to their operation and yet falls apart before any nontrivial program has a chance to run to completion.
Detailed explanation-2: -Quantum computing shows significant promise in various fields, including weather forecasting, artificial intelligence, medical research, etc. However, it poses a substantial threat to cybersecurity, necessitating a shift in how we secure our data.
Detailed explanation-3: -What is quantum computing and why is it important for security? Some digital encryption uses complex mathematical operations that regular computers aren’t efficient enough to solve. However, quantum mechanics may pave the way for computers that can solve them, revealing keys for exchanging data.
Detailed explanation-4: -The major concern with quantum computing is how easily it will crack data transmission cryptography algorithms. The asymmetric RSA algorithm, for example, which is based on integer factoring and provides sufficient security on classical computers, will be breakable on quantum computers.
