We propose a protocol that allows to assess the precise correspondence between thought and practical experiments, a critical point for addressing experimental clumsiness in a test of macro- or micro-realism. Two-time generalized von Neumann measurements of properties ##IMG## [http://ej.iop.org/images/1367-2630/22/7/073047/njpab9ae1ieqn1.gif] {$\mathcal{A}$} and ##IMG## [http://ej.iop.org/images/1367-2630/22/7/073047/njpab9ae1ieqn2.gif] {$\mathcal{B}$} are shown to obey the so-called no-signaling in time condition for initial states defined as an incoherent sum of eigenstates of ##IMG## [http://ej.iop.org/images/1367-2630/22/7/073047/njpab9ae1ieqn3.gif] {$\mathcal{A}$} . An experiment for witnessing the use of this type of measurements in the laboratory is then devised by proving the existence of five conditions that have to be fulfilled by any generalized von Neumann measurement. Ensuring the use of this type of me...

从微观现实到宏观现实：用半弱测量解决实验笨拙

我们提出了一种协议，该协议可以评估思想实验与实际实验之间的精确对应关系，这是解决宏观或微观现实主义测试中实验笨拙的关键点。属性的两次广义冯·诺依曼测度## IMG ## [http://ej.iop.org/images/1367-2630/22/7/073047/njpab9ae1ieqn1.gif] {$ \ mathcal {A} $}和## IMG ## [http://ej.iop.org/images/1367-2630/22/7/073047/njpab9ae1ieqn2.gif] {$ \ mathcal {B} $}都服从所谓的初始状态的时间条件无信号定义为## IMG ##本征状态的不相干总和[http://ej.iop.org/images/1367-2630/22/7/073047/njpab9ae1ieqn3.gif] $ \ mathcal {A} $}。然后，通过证明存在任何任何广义冯·诺依曼测量都必须满足的五个条件，来设计一个实验来证明在实验室中使用这种类型的测量。确保使用这种类型的我...
