检测不兼容的属性

检测不兼容的属性而无需擦除

Detection of incompatible properties without erasure

在这项工作中，我们表明，在双缝实验中，可以检测到与哪条缝属性不兼容的属性，而不会擦除每个粒子通过哪条缝的知识，也不会影响最终屏幕上的撞击点。一个系统的程序来找到这些特定的属性。提出了一种实现这种检测的思想实验。

双缝实验中不相容性质的同时无扰探测

Simultaneous non-disturbing detection of incompatible properties in double-slit experiment

我们利用的概念，其中狭缝检测器介绍的恩格勒，斯库利和瓦尔特（ESW），表明两个不相容的属性可以一起检测到每个粒子击中屏幕，而不干扰质心运动的粒子。

如何在双缝实验中产生量子纠缠以确定不相容性质

How to produce quantum entanglement for ascertaining incompatible properties in double-slit experiments

双缝实验非常适合描述同时测量不相容性质的问题。在这样的背景下，我们从理论上设计了一个理想的自旋为7/2的粒子实验，能够产生纠缠，使检测成为可能。

利用局部性实现不相容性质的同时实在元素

Simultaneous elements of reality for incompatible properties by exploiting locality

我们表明，扩展的量子相关性源于爱因斯坦，波多尔斯基和罗森的现实的标准的“严格”的解释提出了他们的理想实验的不充分的现实的同时元素分配给两个不相容的属性。然后，我们提出了一个不同的物理情况，使同时分配的两个不兼容的观测值的自旋粒子的第二个相关的自旋粒子的两个兼容的属性的测量装置的目标值。

Superposition and time delay are incompatible between them

We analyse the properties of wave functions $ψ(x,t;y,s)$ that depend at once on two time-position vectors $(x,t)$ and $(y,s)$ with different time entries $t\neq{s}$. In particular, we prove that the existence of such wave functions is indeed incompatible with the superposition property and the technique of separation of variables.

State-independent Uncertainty Relations and Entanglement Detection

The uncertainty relation is one of the key ingredients of quantum theory. Despite the great efforts devoted to this subject, most of the variance-based uncertainty relations are state-dependent and suffering from the triviality problem of zero lower bounds. Here we develop a method to get uncertainty relations with state-independent lower bounds. The method works by exploring the eigenvalues of a Hermitian matrix composed by Bloch vectors of incompatible observables and is applicable for both pure and mixed states and for arbitrary number of N- dimensional observables. The uncertainty relation…
