Self-testing of physical theories, or, is quantum theory optimal with respect to some information-processing task?. (arXiv:2003.00349v3 [quant-ph] UPDATED) 上午9:18 | Mirjam Weilenmann, Roger Colbeck | quant-ph updates on arXiv.org Self-testing usually refers to the task of taking a given set of observed correlations that are assumed to arise via a process that is accurately described by quantum theory, and trying… Read more →

Information geometry in quantum field theory: lessons from simple examples. (arXiv:2001.02683v1 [hep-th]) 上午10:07 | Johanna Erdmenger, Kevin T. Grosvenor, Ro Jefferson | quant-ph updates on arXiv.org Motivated by the increasing connections between information theory and high-energy physics, particularly in the context of the AdS/CFT correspondence, we explore the information geometry associated to a variety of simple systems. By studying their… Read more →
