Adaptive versus non-adaptive strategies for quantum channel discrimination
arXiv:0909.0256 · doi:10.1103/PhysRevA.81.032339
Abstract
We provide a simple example that illustrates the advantage of adaptive over non-adaptive strategies for quantum channel discrimination. In particular, we give a pair of entanglement-breaking channels that can be perfectly discriminated by means of an adaptive strategy that requires just two channel evaluations, but for which no non-adaptive strategy can give a perfect discrimination using any finite number of channel evaluations.
