We
have looked at how a transistor works, the fundamental unit of
classical computers, and how a quantum computer works in theory, taking
advantage of quantum superposition to hold exponentially more
information than classical computers. Now we look at the practical side
of making a quantum bit, or qubit. How do you put it in a state where it
is stable? How do you read and write information on it? These processes
are described for a solid state qubit - a phosphorous atom in a silicon
crystal substrate. Both the electron and the nucleus of the phosphorous
atom can be used as qubits.

Thanks to Henry Reich (MinutePhysics) for pushing me to make the explanations and visualizations clearer.
