标题： Probing hierarchy of temporal correlation requires either generalised measurement or nonunitary evolution

摘要： 时间量子态隐形和Leggett-Garg不等式的违背是两种不同的方法，用于探测量子力学中宏观实在性假设的违背。 这里显示，在单位演化和投影测量下，这两种时间相关性会导致相似的结果。 然而，如果其中任何一个被放松，即通过采用广义测量或噪声演化，它们的非等价性可能会表现出来，正如我们在这里用相关例子所示。 显示英文摘要

摘要： Temporal steering and violation of the Leggett-Garg inequality are two different ways of probing the violation of macro-realistic assumptions in quantum mechanics. It is shown here that under unitary evolution and projective measurements the two types of temporal correlations lead to similar results. However, their inequivalence may be exhibited if either one of them is relaxed, i.e., by employing either generalized measurements, or noisy evolution, as we show here using relevant examples.
