Thanks for my boss’s support, I have a chance to give a poster presentation on International Conference on Quantum Optics, Hong Kong. The name of it is “Simple Schemes of CQED for Realizing Swap, Entangling and CNOT Quantum Gate”, which can be found in this webpage. Here is the tentative abstract of the presentation.
We consider the two cavities which are spatially separated and connected by an optical fibre. There are multi Lambda atoms in each of the cavities. The atoms are resonantly interacting to fields and there is no direct interaction between the atoms. We show that perfect swap, entangling and CNOT quantum gates can be realized between the two atoms clusters. Compared with the single atom scheme, we find that the atoms clusters scheme can increase the speed of swap, entangling and CNOT gates. The sensibility of these gates to parameters in the models with consideration is investigated. Finally we take account the effect of dissipation and show that such gates are almost feasible with the present technology.
This is the first time I attend the academic conference and do presentation in English. I wish I can do it well.
