Thirty years after it was first proposed, quantum teleportation remains one of the most
important protocols in quantum information and quantum technologies, enabling the …

Over the past few decades, significant progress has been made in quantum information
technology, from theoretical studies to experimental demonstrations. Revolutionary quantum …

A quantum internet that connects remote quantum processors, should enable a number of
revolutionary applications such as distributed quantum computing. Its realization will rely on …

Optical photons are powerful carriers of quantum information, which can be delivered in free
space by satellites or in fibers on the ground over long distances. Entanglement of quantum …

Global-scale quantum communication links will form the backbone of the quantum internet.
However, exponential loss in optical fibres precludes any realistic application beyond few …

Quantum internet gives the promise of getting all quantum resources connected, and it will
enable applications far beyond a localized scenario. A prototype is a network of quantum …

We report on the quantum storage of a heralded frequency-multiplexed single photon in an
integrated laser-written rare-earth doped waveguide. The single photon contains 15 discrete …

Quantum secure direct communication (QSDC) is capable of direct confidential
communications over a quantum channel, which is achieved by dispensing with the key …

Quantum repeaters based on heralded entanglement require quantum nodes that are able
to generate multimode quantum correlations between memories and telecommunication …

Reversible entanglement transfer between light and matter is a crucial requisite for the
ongoing developments of quantum information technologies. Quantum networks and their …
