## About Quantum Computing
Quantum computing is a type of computing that uses quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data. These operations can be performed much faster than those of classical computers, and can also be used to solve problems that classical computers cannot.

In a classical computer, data is stored and processed using bits, which can have a value of either 0 or 1. In a quantum computer, data is stored and processed using quantum bits, or qubits, which can be in a state of superposition, meaning they can be in multiple states at the same time. This allows quantum computers to perform certain types of calculations much more quickly than classical computers.

One of the most famous example of a problem that is hard for classical computers but easy for quantum computers is known as the factoring problem. Factoring is the process of finding the prime numbers that multiply together to form a given number. For example, if the given number is 12, the prime factors are 2 and 3, because 2 x 3 = 12. Factoring is a hard problem for classical computers because the number of steps required to factor a large number grows rapidly as the number becomes larger. But for Quantum computers, it can be solved in a polynomial time.

Quantum computers are still in the early stages of development, and there are many challenges that must be overcome before they can be used for practical applications. These include issues related to the control of quantum systems, the manipulation of quantum states, and the development of algorithms that can be run on a quantum computer.

While still in early development stage, It has vast potential for areas like cryptography, drug discovery, optimization and machine learning.
