Scope

Quantum engineering of devices is a new field which has been initiated by basic research in quantum information and communication. However, quantum engineering goes much beyond quantum bits and aims to exploit the large diversity of quantum degrees in nanoscaled solid state devices. Today, it is feasible to couple the photonic eigenmodes of an electromagnetic cavity defined by a superconducting waveguide, for example, to an ultraclean suspended carbon nanotube, thereby establishing novel superposition states between different degrees of freedom. Mechanical and electrical degrees may thereby become entangled. Similarly, quantum entanglement can be mediated from Cooper pairs of a superconductor into double quantum dot structures and new exotic states can form at the interface of a wire with one-dimensional spin-orbit bands. The present conference shall focus on these and other engineered hybrid nanodevices, i.e. combination of high quality low-dimensional materials, such as semiconducting nanowires, carbon nanotubes or graphene, with nanostructured superconducting and ferromagnetic materials. These systems provide versatile experimental platforms for the exploration of a wide range of novel quantum phenomena. The unique behavior of hybrid nanodevices is based on the interplay of the macroscopic quantum state of superconductors or ferromagnets and the special properties of nanostructures, like their low dimensionality, ballistic transport or the ability to manipulate charge and spin at the single electron level. Hybrid nanodevices allow to investigate such phenomena like unconventional superconductivity, proximity-induced electron correlations, generation and detection of electron entanglement, manipulation of spin information or the formation of topologically protected quasiparticles, like Majorana fermions. The conference will provide an overview of the recent achievements and breakthroughs of this very active and dynamically developing field.
