标题： High--N00N State Generation: N00N State Output of Floquet Engineering

摘要： 在这里，我们回顾了一些专为制备NOON态（一种在量子计量学应用中至关重要的双部分最大纠缠态）而设计的量子架构。 这些方案背后的基本概念是将初始态$|N\rangle \otimes |0\rangle$转化为NOON态$\frac{1}{\sqrt{2}} (|N\rangle \otimes|0\rangle +|0\rangle \otimes|N\rangle)$，其中$|N\rangle$和$|0\rangle$是具有$N$和$0$激发数的Fock态。 我们证明这种状态可以作为量子光模式的叠加态生成，也可以是光和运动的组合，或者两个自旋系综的叠加态。 这里讨论的方法能够生成介观和宏观纠缠态，例如纠缠相干态和压缩态等。 我们还表明，这类架构可以实现大量最大纠缠态。 此外，还讨论了将这些态制备方法扩展到多模态设置的可能性。 显示英文摘要

摘要： Here, we review some quantum architectures designed for the engineering of the N00N state, a bipartite maximally entangled state crucial in quantum metrology applications. The fundamental concept underlying these schemes is the transformation of the initial state $|N\rangle \otimes |0\rangle$ to the N00N state $\frac{1}{\sqrt{2}} (|N\rangle \otimes|0\rangle +|0\rangle \otimes|N\rangle)$, where $|N\rangle$ and $|0\rangle$ are the Fock states with $N$ and $0$ excitations. We show that this state can be generated as a superposition of modes of quantum light, a combination of light and motion, or a superposition of two spin ensembles. The approach discussed here can generate mesoscopic and macroscopic entangled states, such as entangled coherent and squeezed states, as well. We show that a large class of maximally entangled states can be achieved in such an architecture. The extension of these state engineering methods to the multi-mode setting is also discussed.
