论文摘要
在我们先前的研究中，模拟表明，在子腔中具有同源性检测的量子锁定方案有效地超过了在有限的频率范围内Deci-Hertz干涉仪重力波动台（DECIGO）的量子噪声极限。这次，我们在量子锁定方案的子腔中模拟了光弹性效应。我们发现，与没有光弹簧效应的情况相比，优化的总量子噪声在更广泛的频带中降低，从而显着提高了Decigo对原始引力波的敏感性。
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.
