Controlled few-particle quantum states in an optical cavity QED system (A01)

我们提出在光学谐振腔中实验产生、探测和表征多个中性原子的纠缠态。为了实现这一目标，我们将使用开放系统工程。而不是完全抑制或补偿与环境的所有相互作用，我们将定制和控制耗散损耗，以使量子系统处于所需的纠缠态。我们的研究的预期成果是把有前途的耗散方法变成一个实验建立的方法，用于可靠地制备纠缠态中的少原子量子系统。

We propose to experimentally generate, detect and characterize entangled states of multiple neutral atoms inside an optical resonator. In order to achieve this goal we will use open system engineering. Rather than completely suppressing or compensating all interactions with the environment we will tailor and control dissipative losses to prepare the quantum system in a desired entangled state. The anticipated outcome of our research is to turn the promising dissipative approach into an experimentally established method for reliably preparing few-atom quantum systems in entangled states.
