压缩迭加态的时间演化与反聚束效应破坏的条件

On Time Evolution of Squeezing Superposition States and the Condition to Destroy Anti—bunching

本文研究了压缩迭加态的时间演化,找到了能产生和保持这种压缩态的哈密顿量:真空态与单个光子Fock态的迭加来自于单光子与三光子共存的过程;真空态与两个光子Foek态的迭加来自于双光子和四光子共存的过程。我们还得到了任意两个Fock态迭加后反聚束破坏的条件。

In this paper, we have studdied the time evolution of spueezing superposition states, and have found the Hamiltonian which can produce and preserve the states. The superposition of vacuum state and singl photon Fock state comes from the process in which one photon process and three photons process exist together. The superposition of vacuum state and two-photon Fock state comes from the process in which two photons and four photons process exist together. We also get the condition to destroy anti-bunching after arbitary two Fock states are superposited.
