论文摘要
在假设每个材料对象最终都可以通过量子理论描述的假设，我们询问探针系统如何在设备中演变并保持其经典参数的叠加状态。我们发现，在理想的条件下，系统的演变将是统一的，由有效的哈密顿人产生。我们还描述了对在合奏上实现相同有效演变的设备的不连贯使用。因此，因此产生的有效的哈密顿量可能具有与相关的参数的经典值具有质量不同的特征。
Under the assumption that every material object can ultimately be described by quantum theory, we ask how a probe system evolves in a device prepared and kept in a superposition state of values of its classical parameter. We find that, under ideal conditions, the evolution of the system would be unitary, generated by an effective Hamiltonian. We describe also an incoherent use of the device that achieves the same effective evolution on an ensemble. The effective Hamiltonian thus generated may have qualitatively different features from that associated to a classical value of the parameter.
