论文摘要
虽然量子探针肯定会感觉到重力，但尚未在离域量子状态下制备重力来源。需要解决两个基本问题：如何将足够大的质量定位到产生可检测的重力；而且，一旦准备好了该州，如何通过腐烂来打击本地化。我们建议通过通过ZENO效应在所需状态下冻结来源来抵抗破坏。可以通过在源产生的有效电位中散布探针来验证成功的实现。除了提出这个想法外，我们还提供了可行的提案所需的参数值的估计。总体而言，尽管具体挑战是不同的（例如，不需要保留或检测到纠缠，但必须实施Zeno冻结）。
While quantum probes surely feel gravity, no source of gravity has been prepared in a delocalized quantum state yet. Two basic questions need to be addressed: how to delocalize a mass sufficiently large to generate detectable gravity; and, once that state has been prepared, how to fight localization by decoherence. We propose to fight decoherence by freezing the source in the desired state through the Zeno effect. Successful implementation can be verified by scattering a probe in the effective potential generated by the source. Besides putting forward the idea, we provide an estimation of the values of the parameters required for the proposal to be feasible. Overall, the proposal seems as challenging as other existing ones, although the specific challenges are different (e.g. no entanglement needs to be preserved or detected, but the Zeno freezing must be implemented).
