具有光场正交幅值的连续变量量子信息处理有利于高斯纠缠的确定性产生。另一方面，非高斯态的制备和操作目前是有限的，但预告方案有可能克服这一困难。本文综述了连续变量量子光学实验的最新进展。特别是，我们最近成功地创造了具有完全不可分性的超大尺度簇型纠缠，在时域内复用；预报单光子态的存储和按需释放，应用于两个预报单光子态的同步；具有指数上升波包的非高斯单光子态的实时正交测量利用三角光参量振荡器压缩带宽相对较宽。
Continuous-variable quantum information processing with optical field quadrature amplitudes is advantageous in deterministic creation of Gaussian entanglement. On the other hand, non-Gaussian state preparation and operation are currently limited, but heralding schemes potentially overcome this difficulty. Here, we summarize our recent progress in continuous-variable quantum optical experiments. In particular, we have recently succeeded in creation of ultra-large-scale cluster-type entanglement with full inseparability, multiplexed in the time domain; storage and on-demand release of heralded single-photon states, which is applied to synchronization of two heralded single-photon states; real-time quadrature measurements regarding non-Gaussian single-photon states with exponentially rising wavepackets; squeezing with relatively broader bandwidth by using triangle optical parametric oscillator.
