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.

生成具有任意复杂幅度分布的压缩状态

压缩态在量子计量学和量子信息中很重要。已知的最有效的生成工具是光学参量振荡器 (OPO)。目前，OPO 只能生成低阶空间模式的压缩状态。然而，高阶复杂空间模式的压缩态对于量子计量、量子成像和量子信息等应用更有用。未来应用的一个主要挑战是高效发电。在这里，我们使用级联的仅相位空间光调制器来调制入射基模压缩状态的幅度和相位。这有效地生成了一系列压缩的高阶 Hermite-Gauss 模式和压缩的任意复振幅分布模式。该方法可能会在生物光子学中产生新的应用，
