In spite \smallskip of their popularity the \QTR{bf}{H}eisenberg's (``uncertainty'') \QTR{bf}{R}elations (HR) still generate controversies. The \QTR{bf}{T}raditional \QTR{bf}{I}nterpretation of HR (TIHR) dominate our days science, although over the years a lot of its defects were signaled. These facts justify a reinvestigation of the questions connected with the interpretation / significance of HR. Here it is developped such a reinvestigation starting with a revaluation of the main elements of TIHR. So one finds that all the respective elements are troubled by insurmountable defects. Then it results the indubitable failure of TIHR and the necessity of its abandonment. Consequently the HR must be deprived of their quality of crucial physical formulae. Moreover the HR are shown to be nothing but simple fluctuations formulae with natural analogous in classical (non-quantum) physics. The description of the maesuring uncertainties (traditionally associated with HR) is approached from a new informational perspective. The Planck's constant $\hbar $ (also associated with HR) is revealed to have a significance of generic indicator for quantum stochasticity, similarly with the role of Boltzmann's constant k in respect with the thermal stochasticity.
Anisotropy and Magnetic Field Effects on the Genuine Multipartite Entanglement of Multi-Qubit Heisenberg {\it XY} Chains
研究表明，对于两量子比特海森堡XY模型，通过调节外部磁场超过某个有限的临界强度，各向异性和磁场可以一起用于产生任何有限温度下的纠缠。这个有趣的结果来自于使用Wootters并发度的分析，Wootters并发度是两个量子比特状态的纠缠的可计算度量。最近，Mintert { \em et al.}提出了Wootters并发多体状态的推广。这些MKB并发具有数学性质，使人们能够理解这种特征行为的起源。本文首先利用MKB共存研究了各向异性和磁场对四量子比特海森堡XY链多体热纠缠的影响。我们表明，该模型表现出的特征行为类似于双量子比特模型。此外，我们表明，这可以再次理解使用相同的数学属性。接下来，我们证明了六量子比特海森堡XY链也具有使其具有特征行为所必需的性质。最重要的是，可以直接测量纯态的多体MKB共存。这可能为我们的猜想提供了实验验证，即对于任何偶数量子比特的海森堡XY链，通过施加足够大的磁场，总是可以在任何有限温度下获得非零的真正的多体纠缠。
