量子逻辑和并发性之间

Between quantum logic and concurrency

Luca Bernardinello, Carlo Ferigato, Lucia Pomello

摘要:

我们从定义在一种特殊的偏序集(称为因果网)的元素上的两个闭包算子开始。因果网用于模拟并发进程的历史,记录局部状态和事件的发生。如果这样的偏序集的每个极大链(线)满足每个极大反链(割),则这两个闭包算子重合,并生成一个完备的正交模格。在本文中,我们回顾,在这个格中的任何封闭的集合,每一条线满足它或它的正交补在格中,并表明,任何线,在格上的二值状态可以相关联。从这个结果开始,我们描绘了一种逻辑语言,其公式在因果网的闭集上进行解释,其中每行都诱导公式的真值分配。由此产生的逻辑是非经典的,我们表明,最大的反链在因果网相关联的布尔(因此“经典”)子结构的整体量子逻辑。

英文摘要:

We start from two closure operators defined on the elements of a special kind of partially ordered sets, called causal nets. Causal nets are used to model histories of concurrent processes, recording occurrences of local states and of events. If every maximal chain (line) of such a partially ordered set meets every maximal antichain (cut), then the two closure operators coincide, and generate a complete orthomodular lattice. In this paper we recall that, for any closed set in this lattice, every line meets either it or its orthocomplement in the lattice, and show that to any line, a two-valued state on the lattice can be associated. Starting from this result, we delineate a logical language whose formulas are interpreted over closed sets of a causal net, where every line induces an assignment of truth values to formulas. The resulting logic is non-classical; we show that maximal antichains in a causal net are associated to Boolean (hence "classical") substructures of the overall quantum logic.
