We implement the squeezing operation as a genuine quantum gate, deterministically and reversibly acting `online' upon an input state no longer restricted to the set of Gaussian states. More specifically, by applying an efficient and robust squeezing operation for the first time to non-Gaussian states, we demonstrate a two-way conversion between a particle-like single-photon state and a wave-like superposition of coherent states. Our squeezing gate is reliable enough to preserve the negativities of the corresponding Wigner functions. This demonstration represents an important and necessary step towards hybridizing discrete and continuous quantum protocols.

半导体微结构中的空穴极化激元是研究多体系统非平衡动力学的一个很有前途的系统。在这一领域的关键进展，包括观察极化子凝聚，超流性，实现拓扑光子带，和耗散相变，一般允许基于平均场Gross-Pitaevskii形式主义的描述。虽然观察到极化子强度压缩和极化子凝聚体对极化纠缠光子对的退相干提供了反例，但这些实验中的量子效应在高极化子占有率下表现出来。超越强相关极化激元的机制需要观察光子阻塞效应，其中相互作用足够强以抑制光子晶格位点的双重占据。在这里，我们报告的观察极化激元之间的量子相关性在光纤腔中，空间限制极化激元到3 $μ$ m $^2$的区域。光子相关测量表明，仔细调整耦合系统可以产生适度的光子封锁效应，同时产生双极化子的可能性降低5%即可证明这一点。同时，我们的实验提供了一个明确的测量极化激元相互作用的强度，从而解决了最近的实验报告所产生的争议。我们的发现构成了实现强相互作用光子系统的第一个重要步骤。
