The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Quantum technologies exploit entanglement to revolutionize computing, measurements, and
communications. This has stimulated the research in different areas of physics to engineer …

We report on an elementary quantum network of two atomic ions separated by 230 m. The
ions are trapped in different buildings and connected with 520 (2) m of optical fiber. At each …

Large-scale quantum networks promise to enable secure communication, distributed
quantum computing, enhanced sensing and fundamental tests of quantum mechanics …

Efficient interfaces between photons and quantum emitters form the basis for quantum
networks and enable optical nonlinearities at the single-photon level. We demonstrate an …

Optical communication channels have redefined the scope and applications of classical
computing; similarly, photonic transfer of quantum information promises to open new …

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 …

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 …

The first generation of quantum computers are on the horizon, fabricated from quantum
hardware platforms that may soon be able to tackle certain tasks that cannot be performed or …

Many proposals to scale quantum technology rely on modular or distributed designs
wherein individual quantum processors, called nodes, are linked together to form one large …
