Title: Entanglement in block-scalable and block-scaled states
Title: 块可扩展和块缩放状态中的纠缠
Abstract: We consider the two-qubit sender's initial states whose transfer along a spin-1/2 chain results in multiplying the MQ-coherence matrices by a scalar factor and show that the entanglement in the state transferred in this way is, generally, significantly less than the entanglement in the sender's initial state. We reveal some features of these entanglements using the perturbations of the sender's initial state. The chains of 6 and 42 spin-1/2 particles are considered as examples.
