Abstract | |
The understanding of ultralong-range interaction involving cold Rydberg atoms is the main step for use this system in quantum computation. In this work, we have studied interaction involving $nD$ states in a new experimental setup, which allows us to control the electric field in a more efficient way. More specifically, we have studied the collision process $nD + nD ightarrow (n+2)P + (n-2)F$ in the presence of a static electric field. This process is important because it can lead to a decoherence of the sample. The observed results show the existence of a molecular resonance which is dependent of Stark effect. Moreover, the atomic motion is perhaps also important to populate such states. Finally, we propose new experiments that can be useful to control and to suppress theses colisional processes and in this way allows us to move on in quantum computing area with such systems.
