Regular computers process data as binary bits i.e., either 0 or 1, it stores information as a 0 or 1 whereas a quantum bit (called as a qubit) can be both a 0 and 1 at the same time, and this allows multiple computations happen simultaneously. This is the thing which separates ordinary computers with a quantum computer.

This makes it possible to store vast amounts of information with a relatively small amount of particle.

Quantum computers are good at the thing that has a small input and output while having a vast number of possibilities.

They are designed to do certain task exponentially faster than normal computers.

Quantum computers can do the calculations in the hours which normal or classical computer will take years to solve it.
