摘要:

在我们以前的研究中,模拟表明子腔零差探测的量子锁定方案可以有效地在有限的频率范围内超越分赫兹干涉引力波天文台(DECIGO)的量子噪声极限。这次我们模拟了量子锁定方案子腔中的光学弹簧效应。我们发现优化后的总量子噪声在更宽的频带内降低,与没有光学弹簧效应的情况相比,显著提高了DECIGO对原始引力波的灵敏度。

英文摘要:

In our previous research, simulation showed that a quantum locking scheme with homodyne detection in sub-cavities is effective in surpassing the quantum noise limit for Deci-hertz Interferometer Gravitational Wave Observatory (DECIGO) in a limited frequency range. This time we have simulated an optical spring effect in the sub-cavities of the quantum locking scheme. We found that the optimized total quantum noise is reduced in a broader frequency band, compared to the case without the optical spring effect significantly improving the sensitivity of DECIGO to the primordial gravitational waves.
