论文摘要
我们提出了一项方案，以确定性地制备在较大的光子数状态下的电磁场。该领域以连贯的状态开始，并通过与一个或几个两级系统的谐振相互作用，它将演变成一个连贯位移的Fock状态，而无需任何后选择。我们在现实参数下显示了该方案的可行性。提出的方法打开了一扇门，以$ n \ sim100 $和超过$ 70 $％％的最佳保真度到达Fock状态，模糊了宏观和量子状态之间的界限。
We present a protocol to deterministically prepare the electromagnetic field in a large photon number state. The field starts in a coherent state and, through resonant interaction with one or few two-level systems, it evolves into a coherently displaced Fock state, without any post-selection. We show the feasibility of the scheme under realistic parameters. The presented method opens a door to reach Fock states with $n\sim100$ and optimal fidelities above $70$%, blurring the line between macroscopic and quantum states of the field.
