论文摘要
挤压状态在量子计量和量子信息中很重要。已知最有效的生成工具是光学参数振荡器（OPO）。当前，只能由OPO生成低阶空间模式的挤压状态。但是，高阶复合空间模式的挤压状态对于诸如量子计量，量子成像和量子信息等应用更有用。未来应用的主要挑战是有效的一代。在这里，我们使用级联的仅相位空间光调节器来调节入射基本模式的振幅和相位挤压状态。这有效地生成了一系列挤压的高阶Hermite-gauss模式和挤压任意的复杂振幅分布模式。该方法可能会在生物光谱，量子计量和量子信息处理中产生新的应用。
The squeezed state is important in quantum metrology and quantum information. The most effective generation tool known is the optical parametric oscillator (OPO). Currently, only the squeezed states of lower-order spatial modes can be generated by an OPO. However, the squeezed states of higher-order complex spatial modes are more useful for applications such as quantum metrology, quantum imaging and quantum information. A major challenge for future applications is efficient generation. Here, we use cascaded phase-only spatial light modulators to modulate the amplitude and phase of the incident fundamental mode squeezed state. This efficiently generates a series of squeezed higher-order Hermite-Gauss modes and a squeezed arbitrary complex amplitude distributed mode. The method may yield new applications in biophotonics, quantum metrology and quantum information processing.
