Distributed quantum networks will allow users to perform tasks and to interact in ways which
are not possible with present-day technology. Their implementation is a key challenge for …

We perform a review of various approaches to the implementation of quantum memories,
with an emphasis on activities within the quantum memory sub-project of the EU integrated …

Most quantum communication tasks need to rely on the transmission of quantum signals
over long distances. Unfortunately, transmission of such signals is most often limited by …

Realization of a quantum interface between stationary and flying qubits is a requirement for
long-distance quantum communication and distributed quantum computation. The prospects …

Hyperentanglement is a promising resource in quantum information processing with its high
capacity character, defined as the entanglement in multiple degrees of freedom (DOFs) of a …

Physics and information are intimately connected, and the ultimate information processing
devices will be those that harness the principles of quantum mechanics. Many physical …

Interactions between single spins and photons are essential for quantum networks and
distributed quantum computation. Achieving spin–photon interactions in a solid-state device …

By performing a full analysis of the projected local density of states (LDOS) in a photonic
crystal waveguide, we show that phase plays a crucial role in the symmetry of the light …

We propose an interface between the spin of a photon and the spin of an electron confined
in a quantum dot embedded in a microcavity operating in the weak-coupling regime. This …

In recent years, the physics community has experienced a revival of interest in spin effects in
solid state systems. On one hand, the solid state systems, particularly, semiconductors and …
