论文摘要
我们提出了在旋转系统中共同耦合到玻感模式的旋转系统中创建有用的纠缠状态的协议,直接适用于捕获的离子和腔QED设置。该协议使用这些系统中自然产生的自旋 - 玻色子相互作用的连贯操作,以使自旋挤压状态的及时快速准备。我们通过分析这些系统中的自然反应源的影响来证明协议的鲁棒性,并与更慢的较慢的方法相比,在随着时间的时间产生了纠缠的方法,它们的优势与更较慢的方法相比。
We propose protocols for the creation of useful entangled states in a system of spins collectively coupled to a bosonic mode, directly applicable to trapped-ion and cavity QED setups. The protocols use coherent manipulations of the spin-boson interactions naturally arising in these systems to prepare spin squeezed states exponentially fast in time. We demonstrate the robustness of the protocols by analyzing the effects of natural sources of decoherence in these systems and show their advantage compared to more standard slower approaches where entanglement is generated algebraically with time.
