Ordinary computers store data by using signals consisting of 0's and 1's representing the absence of a signal or the presence of one. There are no 'half' signals, or other ways of storing data. There is only On, and Off.
In a quantum computer, the available states for storing data depend on the states available to an electron. For instance, the data can be stored as spin up or spin down, energy level of the electron, and so on. With these computers, the data storage is more complex, meaning there are fewer elements required to store the same amount of data. Now, for the computation benefits... Quantum effects occur instantly or at the speed of light. That means that you could get the output as soon as you give the input. This would be much faster than a traditional computer.

The fact that they don't exist comes to mind.
