量子精密测量:利用薛定谔猫资源探测弱力

Quantum Metrology: Detection of weak forces using Schrodinger Cat resources

Kae Nemoto, W. J. Munro, G. J. Milburn, S. L. Braunstein

摘要:

我们研究了简谐振子的非经典态(相干态的叠加)在灵敏力检测中的应用。我们发现,像压缩态的相干态的叠加允许在海森堡极限位移测量的检测。与具有相同平均光子数的单模叠加态相比,纠缠多个相干态的叠加提供了显著的优势。

英文摘要:

We investigate the utility of non classical states of simple harmonic oscillators (a superposition of coherent states) for sensitive force detection. We find that like squeezed states a superposition of coherent states allows the detection of displacement measurements at the Heisenberg limit. Entangling many superpositions of coherent states offers a significant advantage over a single mode superposition states with the same mean photon number.
