An experimental approach to realize quantum logic gates based atomic Ramsey interferometry is presented in Sect. 6.5. The quantum bits are represented by atoms. A beam of atoms is sent through a microwave resonator. The resonator provides the necessary interaction between the atoms to perform quantum logic gates. This is an example for the concept of flying qubits. Experiments along these lines are carried out at the Ecole Normale Superiore in Paris.
