It is known that a reliable geometric quantifier of discord-like correlations can be built by
employing the so-called trace distance, which is used to measure how far the state under …

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 …

Efficient quantum-state transfer is achieved in a uniformly coupled spin-1/2 chain, with open
boundaries, by application of local magnetic fields on the second and last-but-one spins …

Robust control design for quantum unitary transformations has been recognized as a
fundamental and challenging task in the development of quantum information processing …

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 …

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 …

We study quantum-state transfer in XX spin-1/2 chains where both communicating spins are
weakly coupled to a channel featuring disordered on-site magnetic fields. Fluctuations are …
