Exact State Revival in a Spin Chain with Next-To-Nearest Neighbour Interactions (1610.04796v1)
Published 15 Oct 2016 in quant-ph
Abstract: An extension with next-to-nearest neighbour interactions of the simplest XX spin chain with perfect state transfer (PST) is presented. The conditions for PST and entanglement generation (balanced fractional revival) can be obtained exactly and are discussed.
