我们提出并分析了一种定制量子态波函数的装置。我们的设置是基于量子隐形传态电路，但使用的不是通常的双模压缩态，而是双模非高斯纠缠态。利用这个装置，我们可以产生各种类型的量子态，如薛定谔猫态、四分量猫态、Fock态的叠加态和立方相位态。这些结果证明了我们的系统作为状态发生器的多功能性，并表明使用零差测量的条件作用是产生非高斯态的一个重要工具，它是对光子数检测的补充。
We propose and analyze a setup to tailor the wave functions of quantum states. Our setup is based on the quantum teleportation circuit, but instead of the usual two-mode squeezed state, a two-mode non-Gaussian entangled state is used. Using this setup, we can generate various classes of quantum states such as Schrodinger cat states, four-component cat states, superpositions of Fock states, and cubic phase states. These results demonstrate the versatility of our system as a state generator and suggest that conditioning using homodyne measurements is an important tool in the generation of the non-Gaussian states complementarily to photon number detection.
