One of the essential features required for the realization of a quantum computer is quantum entanglement. A team of physicists from the University of Vienna and the Austrian Academy of Sciences (ÖAW) introduces a novel technique to detect entanglement even in large-scale quantum systems with unprecedented efficiency. This brings scientists one step closer to the implementation of reliable quantum computation. The new results are of direct relevance for future generations of quantum devices and are published in the current issue of the journal Nature Physics.
