Reliable quantum communication and/or processing links between modules are a
necessary building block for various quantum processing architectures. Here we consider a …

Spin chains have been proposed as quantum wires in many quantum-information
processing architectures. Coherent transmission of quantum information in spin chains over …

We study transfer of a quantum state through XX spin chains with static imperfections. We
combine the two standard approaches for state transfer based on (i) modulated couplings …

Spin chains have been proposed as a reliable and convenient way of transferring
information and entanglement in a quantum computational context. Nonetheless, it has to be …

We propose a scheme for parameter estimation with cluster states. We find that phase
estimation with cluster states under a many-body Hamiltonian and separable measurements …

Quantum spin networks can be used to transport information between separated registers in
a quantum-information processor. To find a practical implementation, the strict requirements …

Nuclear spin systems and magnetic resonance techniques have provided a fertile platform
for experimental investigation of quantum state transfer in spin chains. From the first …

Recently there has been much study on the application of spin chains to quantum state
transfer and communication. Here we discuss the utilization of spin chains (set up for perfect …

We discuss entanglement generation in a closed system of one or two atomic quantum dots
(qubits) coupled via Raman transitions to a pool of cold interacting bosons. The system …

This introductory paper aims to provide a brief review of some basic concepts in quantum
optics and quantum information, such as quantization of the electro-magnetic field, Fock and …
