论文摘要
意识到具有大量物体的空间叠加是最根本的挑战之一，因为它将在新的制度，探针量子重力中测试量子理论，并能够检验诸如重力引起的崩溃之类的异国理论。成功实施原子尾grach干涉仪（SGI）的自然扩展是一种具有纳米二蒙蒙德（ND）的SGI，其中单个旋转嵌入了氮气现象中心（NV）的形式。随着ND旋转以及NV自旋方向的旋转，无论是在牛顿轨迹和量子阶段而已抑制了这种实现，我们在这里分析了旋转在SGI中的作用。我们考虑了基本限制，例如由量子角不确定性关系和热波动所施加的限制。我们提供了一个详细的食谱，启用了大规模对象的叠加。这不仅可以为基本测试打开大门，还可以向新的量子技术打开大门。
Realizing a spatial superposition with massive objects is one of the most fundamental challenges, as it will test quantum theory in new regimes, probe quantum-gravity, and enable to test exotic theories like gravitationally induced collapse. A natural extension of the successful implementation of an atomic Stern-Gerlach interferometer (SGI), is a SGI with a nano-diamond (ND) in which a single spin is embedded in the form of a nitrogen-vacancy center (NV). As the ND rotation, and with it the rotation of the NV spin direction, may inhibit such a realization, both in terms of Newtonian trajectories and quantum phases, we analyze here the role of rotations in the SGI. We take into account fundamental limits, such as those imposed by the quantum angular uncertainty relation and thermal fluctuations. We provide a detailed recipe for which a superposition of massive objects is enabled. This may open the door not only to fundamental tests, but also to new forms of quantum technology.
