论文摘要
已经提出，可以通过将重力作为纠缠的中介来实验暴露重力场的量子特征。我们表明，为了在实验上目睹这种类型的纠缠，必须克服对加速度噪声的强大限制，这在以前的工作中忽略了。在两个类似质量的粒子的情况下，Casimir-Polder力会导致每个根赫兹的十分之一平方仪的基本限制。对于两个不等质量颗粒的限制，限制不太严格，具体取决于碰撞的腐蚀。
It has been proposed that quantum features of the gravitational field can be exposed experimentally by employing gravity as a mediator of entanglement. We show that in order to witness this type of entanglement experimentally, strong limits on acceleration noise, which has been neglected in previous work, must be overcome. In the case of two particles of similar mass, Casimir-Polder forces lead to a fundamental limit of tenths of femtometers per second squared per root Hertz. Limits are between three and six orders of magnitude less strict for two particles of unequal mass, depending on collisional decoherence.
