论文摘要
我们表明,尽管无法观察到虚拟颗粒,但可以用量子算子来描述,这些粒子可以在某些条件下解释为有效的量子量子状态。对于单个虚拟费米,我们证明这种状态是具有明确定义的有限温度的可分离的混合2 Quient状态。对于Spin-1虚拟玻色子,我们发现它们与4克操作员相关联,可以将其解释为某些测量值的量子状态。我们还研究了虚拟对的fermions的创建,其中这对被证明与纠缠的4 QUIT运算符相关,并显示相应的量子电路。最后,我们证明重新归一化不会在结构上影响这些结果。这些发现代表了量子场理论,量子信息和量子热力学之间的新联系。
We show that virtual particles, despite being unobservable, can be described by quantum operators which can be interpreted under certain conditions as valid qubit quantum states. For a single virtual fermion, we prove that such a state is a separable mixed 2-qubit state with a well-defined finite temperature. For spin-1 virtual bosons, we find them to be associated to 4-qubit operators which can be interpreted as quantum states for some gauges. We also study the creation of virtual pairs of fermions, where the pair is shown to be associated to an entangled 4-qubit operator, and show the corresponding quantum circuit. Finally, we prove that renormalization does not structurally affect these results. These findings represent new connections between quantum field theory, quantum information and quantum thermodynamics.
