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 …

A future quantum network will consist of quantum processors that are connected by quantum
channels, just like conventional computers are wired up to form the Internet. In contrast to …

Quantum teleportation is an essential capability for quantum networks, allowing the
transmission of quantum bits (qubits) without a direct exchange of quantum information. Its …

Entanglement between stationary quantum memories and photonic channels is the
essential resource for future quantum networks. Together with entanglement distillation, it …

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 …

Interfacing fundamentally different quantum systems is key to building future hybrid quantum
networks. Such heterogeneous networks offer capabilities superior to those of their …

The faithful storage and coherent manipulation of quantum states with matter-systems would
enable the realization of large-scale quantum networks based on quantum repeaters. To …

Entanglement between photons at telecommunication wavelengths and long-lived quantum
memories is one of the fundamental requirements of long-distance quantum communication …
