Fast and robust quantum state transfer (QST) is a major requirement in quantum control and
in scalable quantum information processing. Topological protection has emerged as a …

Pretty good state transfer in networks of qubits occurs when a continuous-time quantum walk
allows the transmission of a qubit state from one node of the network to another, with fidelity …

We consider a coupled-cavity array, where each cavity interacts with an atom under the
rotating-wave approximation. For a staggered pattern of intercavity couplings, a pair of field …

Two different models are presented that allow for efficiently performing routing of a quantum
state. Both cases involve an XX spin chain working as a data bus and additional spins that …

We consider the optimal control of switching on a coupling term between two quantum many-
body systems. Specifically, we (i) quantify the energetic cost of establishing a weak junction …

The long distance entanglement in finite size open Fermi–Hubbard chains, together with the
end-to-end quantum teleportation are investigated. We show the peculiarity of the ground …

We investigate the fidelity of the quantum state transfer (QST) of two qubits by means of an
arbitrary spin-1 2 network, on a lattice of any dimensionality. Under the assumptions that the …

In this paper we propose a superadiabatic protocol where quantum state transfer can be
achieved with arbitrarily high accuracy and minimal control across long spin chains with an …

Generating high-quality multiparticle entanglement between communicating parties is the
primary resource in quantum teleportation protocols. To this aim, we show that the natural …

In this work we study the single-qubit quantum state transfer in uniform long-range spin XXZ
systems in high-dimensional geometries. We consider prototypical long-range spin …
