Quantum computers are machines that use the properties of quantum physics to store data and perform computations. This can be extremely advantageous for certain tasks where they could vastly outperform even our best supercomputers.

Know – Basis of Computer

A conventional digital computer uses electronic circuits on a plate of semiconducting material to represent binary digits, each in a state of either 1 or 0.

## History of Quantum Computer

- The quantum computing was first suggested in 1969, and officially launched in 1980 by Yuri Manin and in 1982 by Richard Feynman.
- In 2014, quantum computing is still in its begineer level, with experiments yielding computations on a small number of qubits.
- On 9 Dec 2015, Google presented its findings that using D-Wave quantum computers could solve some problems 100 million faster than a conventional system.

Quantum computers come in various shapes and forms, but they are all built on the same principle: they host a quantum processor where quantum particles can be isolated for engineers to manipulate.

The nature of those quantum particles, as well as the method employed to control them, varies from one quantum computing approach to another. Some methods require the processor to be cooled down to freezing temperatures, others to play with quantum particles using lasers – but share the goal of finding out how to best exploit the value of quantum physics.
