SUMMARY:
Computer Science revolutionized the processing, transmission and storage of information, leading to some limitations, arose with the minimization of electronic components at the atomic level, to solve this problem a new computational model based on the laws of Quantum Physics was proposed, Computing and Quantum Information, however, building computers with this new theory has proved to be very challenging in the face of experimental limitations. Many models for transmitting information have been proposed and one of the most studied is electronic transport in materials with disorder. One of the most successful models to explain this phenomenon is the Anderson Location model, so the study of crystalline and disordered networks is a strong candidate to assist the development of electronic components to implement these new computers. In this work We investigate a single-qubit state transfer protocol along a channel featuring diagonal diluted disorder. In the regime where the source and destination sites are weakly coupled to the channel, we report the possibility of transmitting quantum states with high fidelity as well as establishing end-to-end entanglement in that sort of configuration. We further discuss how the performance of the protocol depends upon the availability of extended states within the disordered channel.
