Quantum computers are advanced machines that use the rules of quantum physics to process information. They work differently from normal computers. Traditional computers use bits that are either 0 or 1. Quantum computers use qubits, which can be 0 and 1 at the same time. This allows them to handle very large and difficult calculations much faster.

Today, only large organizations, research labs, and universities use quantum computers. They are expensive and need special environments, such as very cold temperatures, to work properly. This makes them impossible to use at home.

In the future, quantum computers may help create new medicines, improve artificial intelligence, solve climate problems, and make better encryption systems. Scientists are still developing this technology, and it will take more time before it becomes available to the general public.
