## The basics of quantum computing

Quantum computing primer

## Try your hand at quantum

The Quantum Card Test lets you experience the difference between a classical computer and a quantum computer. It is a two-qubit example of Grover’s Search, a well-known quantum algorithm, used here to demonstrate the difference between classical and quantum computers. Watch both compete to find the queen.

## What does a quantum computer look like?

A quantum computer looks nothing like the system you have on your desk or in your pocket, though those devices can be used to access a quantum computer via IBM Cloud. IBM's quantum computer places quantum chips inside a refrigerator that is very cold -- colder than outer space -- in order to keep qubits in the proper state to perform calculations. Heat, noise or electromagnetic waves can interfere with this. A quantum computer is major feat of engineering.

## How will quantum computers be used?

Quantum computers may be used to optimize complex logistics -- like how to deliver a product to your door with the least amount of fuel and time or choosing the best financial portfolio. They have the potential to help discover new medicines and materials. IBM believes the most powerful quantum systems of the next decade will be a hybrid of quantum and classical computers able to address problems that are currently unsolvable using classical computers alone, but hold tremendous untapped value.
