+We will look at an approach of building a quantum computer by using trapped ions:
+
+We look at single atoms with one electron orbiting the nucleus.
+The quantum state is encoded as the orbital of the electron.

+## Operations
+
+### Cooling
+
+An ion of energy level $E_i$ when hit by a photon of energy level $E_j-E_i$ will go to energy level $E_j$
