Worldwide, enormous efforts are directed toward the development of the so‐called quantum
internet. Turning this long‐sought‐after dream into reality is a great challenge that will …

The generation, manipulation, storage, and detection of single photons play a central role in
emerging photonic quantum information technology. Individual photons serve as flying …

The long dreamed 'quantum internet'would consist of a network of quantum nodes (solid-
state or atomic systems) linked by flying qubits, naturally based on photons, travelling over …

The development of scalable sources of non-classical light is fundamental to unlocking the
technological potential of quantum photonics. Semiconductor quantum dots are emerging as …

Nanometre-scale semiconductor devices have been envisioned as next-generation
technologies with high integration and functionality. Quantum dots, or the so-called'artificial …

More than 80 years have passed since the first publication on entangled quantum states.
Over this period, the concept of spookily interacting quantum states became an emerging …

Multiscale, hierarchically patterned surfaces, such as lotus leaves, butterfly wings, adhesion
pads of gecko lizards are abundantly found in nature, where microstructures are usually …

This Perspective presents an overview on the epitaxial growth and optical properties of
GaAs quantum dots obtained with the droplet etching method as high-quality sources of …

We prepare symmetry-controlled GaAs/AlGaAs quantum dots (QDs) on (001) GaAs
substrates by infilling GaAs into AlGaAs nanoholes. For the most symmetric QDs, we …

Quantum mechanics promises to have a strong impact on many aspects of research and
technology, improving classical analogues via purely quantum effects. A large variety of …
