Complex quantum systems exhibit a variety of unconventional phenomena, such as protected quantized edge currents or excitations with non-trivial statistics.

Device-independent quantum information processing represents a new framework for quantum information applications in which devices are just seen as quantum black boxes processing classical information.

The design of fundamental optical components such as lenses, gratings, and holograms has remained essentially unchanged for at least fifty years, relying on textbook refractive and diffractive optics.

Synthetic ladders realized with one-dimensional alkaline-earth(-like) fermionic gases and subject to a gauge field represent a promising environment for the investigation of quantum Hall physics with ultracold atoms.

The beauty of topological materials is that their electronic properties can be essentially described by integer topological invariants associated with their band structures.

Future quantum networks will allow the secure distribution of encryption keys over extended distances, blind quantum computing, and networked quantum computers and atomic clocks.

One aspect of metrology, the science of measurement, is the exploration of the ultimate precision limit. It is known for quite some time that the new possibilities in quantum mechanics allow the surpassing of the ultimate classical precision limit given by counting statistics.

Magnetization manipulation is an indispensable tool for both basic and applied research. I will discuss some of the knobs to tune dynamics at ultrafast time scales.

The propagation of light in inhomogeneous media, and in particular in biological tissues, results in wavefront distortions and scattering which impose major limitations in many applications, from microscopy to nanosurgery.

The precision of any measurement is limited by quantum mechanics. Yet, in practice, hardly any measurement reaches its quantum limits. This is because dephasing typically influences measurement device, rendering their sensitivity below its physical limits.

On September 14, 2015 the two LIGO gravitational wave detectors in Hanford, Washington and Livingston, Louisiana registered a coincident signal conforming to the gravitational waveform expected from the merger of two massive, compact objects.

Bose-Einstein condensation has been observed with cold atomic gases, quasiparticles in solid state systems as polaritons, and more recently with photons in a dye-filled optical microcavity.
