摘要:

我们提出了一种能够产生单模辐射场Fock态的装置。该方案是基于耦合信号场的环形腔通过交叉克尔相位调制,并在输出腔模式的条件ON-OFF光电探测。同样的设置允许准备选定的福克态和纠缠双模态的叠加。值得注意的是,探测器的量子效率并不影响状态合成的可靠性。

英文摘要:

We propose a setup capable of generating Fock states of a single mode radiation field. The scheme is based on coupling the signal field to a ring cavity through cross-Kerr phase modulation, and on conditional ON-OFF photodetection at the output cavity mode. The same setup allows to prepare selected superpositions of Fock states and entangled two-mode states. Remarkably, the detector's quantum efficiency does not affect the reliability of the state synthesis.
