AI总结:
本文研究相对论原理对非因子量子系统局部演化的约束,证明可局部应用且不产生超光速信号的演化必为线性、幺正且尊重块分解。
AI中文摘要:
我们考虑了相对论原理对非因子量子系统(如量子时空和因果结构中自然出现的系统)局部演化结构的影响。我们推广了先前针对因子系统给出的结果,证明任何可以局部应用于因子系统直和且不产生超光速信号的演化,必须是线性的、幺正的,并尊重系统的块分解。
英文摘要:
We consider the effect of relativistic principles on the structure of the local evolutions of non-factor quantum systems such as those which naturally arise in quantum spacetimes and causal structures. Generalising a former result that had been given for factor systems, we show that any evolution which can be applied locally on a direct sum of factor systems and without producing superluminal signals must be linear, unitary, and respect the block decomposition of the system.
