Original Title:
Transferring states in quantum networks
Translated title:
Transferring states in quantum networks
Summary:
In this work spin quantum networks are considered as a potential platform for transferring states between two locations. We examine two classes of protocols, one where the network’s parameters are suitably engineered but remain constant through the transfer process and another, where the parameters are time-driven. In the former, we unravel the network’s properties that lead to the phenomenon of Perfect State Transfer and moreover, we consider a scheme for generating entanglement. For the time-driven case, we turn our focus on the form of the driving function. Based on the instantaneous eigenspectrum characteristics, we construct a driving function that leads to a fast and robust state transfer between the two ends of a topological chain.
