摘要

以光学陀螺仪方案为例，提出了一种提高相位测量精度的新方法。在旋转记录马赫-曾德尔干涉仪中，采用双模压缩真空作为输入态。这就不允许实现传统的方案，因为输出端的差分信号的平均值总是零。然而，结果表明，仪器参照系旋转角速度大小的信息包含在差分信号的噪声级中。论证了测量精度达到海森堡极限的可能性。

Noise-oriented quantum optical gyrometry

By the example of an optical gyroscope scheme, a new method for improving the accuracy of phase measurements is considered. In the rotation-recording Mach – Zehnder interferometer, a two-mode squeezed vacuum is used as an input state. This does not allow realising the traditional scheme, since the average value of the difference signal at the output is always zero. However, it is shown that information about the magnitude of the rotation angular velocity of the instrument reference frame is contained in the noise level of the difference signal. The possibility of reaching the Heisenberg limit of the measurement accuracy is demonstrated.
