Artistic impression of entanglement detection. The stream of green and red lights represents the answers required by the protocol, thus revealing the presence of entanglement between photons.
Physicists develop new method to prove quantum entanglement 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". Quantum computation has been drawing the attention of many scientists because of its potential to outperform the capabilities of standard computers for certain tasks. For the realization of a quantum computer, one of the most essential features is quantum entanglement. This describes an effect in which several quantum particles are interconnected in a complex way.
