+We now look at the construction of a single-qubit quantum computer (hypothetical):
+
+We encode the qubit using the excitation of an electron.
+We assume that an electron has only states $\ket{0}$ and $\ket{1}$ with 0 being the ground state.
+The states have energy levels $\pi$ and $2\pi$.
+
+Now we need to be able to do 3 things:
+1. Initialize qubit with $\ket{0}$, also called cooling.
+2. Ability to measure the qubit.
+3. Ability to apply a unitary to qubit.
