Erwin Schrödinger, an Austrian Nobel Prize winner, introduced the German word ``Verschränkung (Englisch: entanglement) for a phenomenon that cannot be explained classically. The Austrian Anton Zeilinger got this year (2022) the Nobel Prize for his experimental studies of this phenomenon. Mathematically, entanglement can be defined exactly, but surprisingly given a quantum state, i.e. the full information available, it is not generally possible to find out whether this state is entangled or not. Those states, that allow no simple detection, are also physically relevant as their entanglement cannot be increased to the maximal entanglement. This kind of entanglement is called ``bound entanglement, in contrast to the ``free entanglement. This project wants on one hand to find novel methods to detect those states, e.g. by utilizing machine learning, a kind of weak artificial intelligence (AI), on the other hand we will explore the structure of bound entanglement and its potential for applications to quantum technologies.
