Need for Quantum computers? Are there real Use Cases?

Quantum System Two, the R & D marvel of IBM was unveiled a year ago. In-house IBM-made chip that powers this futuristic machine is called the Heron. IBM is working to produce a 100,000 qubit Quantum System. It will be ready by 2033.

A qubit is essentially an equivalent of a Bit in the binary computing which is used to encode information. In Quantum Computing that encoding is carried through encoding over the basic unit of information, which is a Qubit. Read more about Qubits here.
