论文摘要
我们分析了相对论量子信息协议中具有或没有量子自由度的相对论领域之间的差异。我们对量子自由度的存在为解释相互作用的量子系统的现象学所必需的量子级别进行分类。我们还确定了相对论量子信息协议中的量子控制经典字段可以很好地近似量子场的精确制度。我们的结果对于识别哪些特征在经典和量子场理论中有很大不同。
We analyze the differences between relativistic fields with or without quantum degrees of freedom in relativistic quantum information protocols. We classify the regimes where the existence of quantum degrees of freedom is necessary to explain the phenomenology of interacting quantum systems. We also identify the precise regimes where quantum fields can be well approximated by quantum-controlled classical fields in relativistic quantum information protocols. Our results can be useful to discern which features are fundamentally different in classical and quantum field theory.
