大Fock态的确定性产生

Deterministic Generation of Large Fock States

M. Uria, P. Solano, C. Hermann-Avigliano

摘要:

我们提出了一个协议,确定性地准备电磁场在一个大光子数的状态。场开始于相干态,通过与一个或几个二能级系统的共振相互作用,它演化成相干位移的Fock态,没有任何后选择。我们证明了该方案的可行性下现实的参数。所提出的方法打开了一扇门,达到Fock态与$n\sim100$和最佳的结晶度以上$70$ %,模糊了宏观和量子态的字段之间的线。

英文摘要:

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.
