论文摘要
我们建立了量子理论对光学椭圆法可以实现的准确性施加的最终限制。我们表明，当入射光处处于连贯状态时，标准量子极限可以通过使用适当的挤压状态而超越，对于量身定制的梁，甚至可以将其推到最终的海森伯格限制。
We establish the ultimate limits that quantum theory imposes on the accuracy attainable in optical ellipsometry. We show that the standard quantum limit, as usual reached when the incident light is in a coherent state, can be surpassed with the use of appropriate squeezed states and, for tailored beams, even pushed to the ultimate Heisenberg limit.
