Squeezing is a crucial resource for quantum information processing and quantum sensing. In levitated nanomechanics, squeezed states of motion can be generated via temporal control of the trapping frequency of a massive particle. However, the amount of achievable squeezing typically suffers from detrimental environmental effects. We propose a scheme for the generation of significant levels of mechanical squeezing in the motional state of a levitated nanoparticle by leveraging on the careful temporal control of the trapping potential. We analyse the performance of such a scheme by fully accounting for the most relevant sources of noise, including measurement backaction. The feasibility of our proposal, which is close to experimental state-of-the-art, makes it a valuable tool for quantum state engineering.

挤压连续监测的悬浮纳米粒子的运动基态以下


压缩是量子信息处理和量子传感的重要资源。在悬浮纳米力学中，可以通过对大质量粒子的捕获频率进行时间控制来产生运动的压缩状态。然而，可实现的挤压量通常会受到有害的环境影响。我们提出了一种方案，通过利用捕获电位的仔细时间控制，在悬浮纳米粒子的运动状态下产生显着水平的机械挤压。我们通过充分考虑最相关的噪声源（包括测量反作用）来分析此类方案的性能。我们的建议的可行性接近最先进的实验水平，使其成为量子态工程的宝贵工具。
