Extension of the remotely creatable region via the local unitary transformation on the receiver side
arXiv:1511.03507
Abstract
We consider the remote state creation via the homogeneous spin-1/2 chain and show that the significant extension of the creatable region can be achieved using the local unitary transformation of the so-called extended receiver (i.e. receiver joined with the nearest node(s)). This transformation is { most} effective in the models with all-node interactions. We consider the model with the two-qubit sender, one-qubit receiver and two-qubit extended receiver.
