| @ Introduction of the project |
| @@A cavity quantum electrodynamics (QED) system, in which an
atom is coupled to the quantized electromagnetic fields (light) of an optical
cavity, can be described with three characteristic parameters: g , the rate of
coherent exchange of energy between an atom and cavity fields, g , the rate of
the decay of the atomic dipole, k , the rate of the decay of the cavity field.
When a cavity has extremely high finesse and small mode volume, the condition
of strong coupling, g >> g , k , can be achieved. In the strong coupling
regime, coherent interaction of light and atom dominates the dissipation of the
system, and single atom gives rise to a strong nonlinearity in optical responses
and nonclassical statistics for light at single-photon level, while single photon
affects the quantum state of the atom. Therefore, in this system, it is possible
to generate highly quantum (nonclassical) states or to observe novel phenomena
which are normally hampered by dissipation in other systems. It is applicable
to quantum information science (e.g., nonclassical light source, scalable quantum
logic with photons, quantum network connected with light), ultra-low threshold
optical device, and single atom/molecule detecting device. In this project, we
utilize a cavity QED system in strong coupling (by using conventional Fabry-Perot
cavities or novel microtoroidal cavities) and develop techniques to coherently
and deterministically control the quantum state of an atom and light and seek
for applications to quantum information science with light. |
