More entanglement implies higher performance in tailored channel discrimination tasks
arXiv:1809.02082 · doi:10.1103/PhysRevLett.122.140404
Abstract
We show that every entangled state provides an advantage in bi- and multi-channel discrimination that singles out its degree of entanglement, quantified in terms of its Schmidt number and of the corresponding robustness measures.
