论文摘要
挤压状态是一种多功能的量子状态类别，其应用范围从量子计算到高精度检测。我们提出了一种生成具有多种模式的频率箱形式的可调式挤压光状态的方法。我们的方法使用脉冲泵场泵送的定制自发参数下调。多模式挤压状态是在单个通过中生成的，可以通过调整泵场的属性来实时调整。探索以新的自由度编码的新的光量子状态可以成为发现新量子应用的富有成果的途径。
Squeezed states are a versatile class of quantum states with applications ranging from quantum computing to high-precision detection. We propose a method for generating tunable squeezed states of light with multiple modes encoded in frequency bins. Our method uses custom-engineered spontaneous parametric downconversion pumped by a pulse-shaped pump field. The multi-mode squeezed states are generated in a single pass and can be tuned in real time by adjusting the properties of the pump field. Exploring new quantum states of light, encoded in new degrees of freedom, can be a fruitful path toward discovering new quantum applications.
