论文摘要
使用传统的杂种读数的精确测量与同性恋读数相比，遭受3DB量子噪声惩罚。额外的噪声是由图像真空中的量子波动引起的。我们提出了一种两载架引力波探测器设计，该设计逃避了异性恋读数的3DB量子惩罚。我们进一步提出了一种新的方法，可以利用我们的方案中的两种模式挤压来实现频率依赖性挤压。它自然会通过射频挤压来实现更精确的音频信号测量。另外，检测器与其他量子非态度技术兼容。
Precision measurements using traditional heterodyne readout suffer a 3dB quantum noise penalty compared with homodyne readout. The extra noise is caused by the quantum fluctuations in the image vacuum. We propose a two-carrier gravitational-wave detector design that evades the 3dB quantum penalty of heterodyne readout. We further propose a new way of realising frequency-dependent squeezing utilising two-mode squeezing in our scheme. It naturally achieves more precise audio frequency signal measurements with radio frequency squeezing. In addition, the detector is compatible with other quantum nondemolition techniques.
