Threats of quantum computing

Quantum computing is an area of computing that deals with quantum theory. We know that every single outcome of any kind of computation is represented in 0s and 1s known as bits. Quantum computing, on the other hand, uses Qubits (quantum bits) instead of bits, that exhibits several states simultaneously rather than being mutually exclusive. This technological advancement could greatly influence performance in existing computing systems.

The performance benefits gained by quantum computing can be used to solve complex computing problems, including cryptographic algorithms that could only be broken by brute-force attacks. We are already aware that blockchain technology achieves most of the functionalities with the ...
