## Quantum computing

## Project Rating

Quantum Computing is one of the best and exciting field which gives more information about computation in quantum level. Quantum Computing is the intersection of mathematics, computer science, physics. as everyone knows computation plays a major role in all the industry without computation nothing is possible in the world Because of this purpose Computers came into existence but these computers couldn’t able to do complex calculation Scientists discovered quantum computers Ordinary computers uses bits for calculation but Quantum computers uses Qubits to perform calculation which is more reliable here in this presentation contains brief description about quantum computers,working principle,representation,its architecture along with future scope of quantum Computers. Quantum computing was started in the early 1980s when Richard Feynman and Yuri Manin expressed the idea that a quantum computer had the potential to simulate things that a classical computer could not. In 1994, Peter Shor published an algorithm that is able to efficiently solve some problems that are used in asymmetric cryptography that are considered hard for classical computers.

#### Why: Problem statement

Quantum computing is the area of study focused on developing computer technology based on the principles of quantum theory, which explains the nature and behaviour of energy and matter on the quantum (atomic and subatomic) level. Developing the quantum computer will have the good performance than Supercomputer because it follows the laws of physics so it will perform tasks using all possible permutations simultaneously. Currently MIT,IBM,Oxford University, Google having centres for research in quantum Computing

#### How: Solution description

Quantum theory's development began in 1900 with a presentation by Max Planck to the German Physical Society, in which he introduced the idea that energy exists in individual units (which he called "quanta"), as does matter. Further developments by a number of scientists over the following thirty years led to the modern understanding of quantum theory.

A quantum computer is a machine that performs calculations based on the laws of quantum mechanics, which is the behavior of particles at the sub-atomic level.

Representation of Quantam Computer:

- Data is represented in form of qubits
- Qubits can be either 0 or 1 or both
- Represent the speed of computer

Principle- SUPERPOSITION: there is an equal probability that something is either in one state (1) or another (0). Thus, something is in both states, or between both states at the same time until observed.

Principle of Entanglement- In quantum physics, entangled particles remain connected so that actions performed on one affect the other, even when separated by great distances. Entanglement occurs when a pair of particles, such as photons, interact physically.

Shor's algorithm is a quantum computer algorithm for integer factorization. Informally, it solves the following problem: Given an integer N find its prime factors. It was invented in 1994 by the American mathematician Peter Shor.
