interaction. Here, we study how this activation protocol can be used to entangle the starting systems themselves via entanglement swapping through a measurement on the ancillae. Furthermore, we bound the relative entropy of quantumness (a naturally arising measure of non-classicality in the scheme of Piani et al. above) for a special class of separable states, the so-called classical–quantum states. In particular, we fully characterize the classical–quantum two-qubit states that are maximally non-classical.}}, author = {{Gharibian, Sevag and PIANI, MARCO and ADESSO, GERARDO and CALSAMIGLIA, JOHN and HORODECKI, PAWEŁ}}, issn = {{0219-7499}}, journal = {{International Journal of Quantum Information}}, number = {{07n08}}, pages = {{1701--1713}}, publisher = {{World Scientific Pub Co Pte Lt}}, title = {{{Characterizing Quantumness via Entanglement Creation}}}, doi = {{10.1142/s0219749911008258}}, volume = {{09}}, year = {{2011}}, } @inproceedings{8176, abstract = {{Approximation algorithms for classical constraint satisfaction problems are one of the main research areas in theoretical computer science.
