Joseph Polchinski: A Biographical Memoir. (arXiv:2002.02371v1 [physics.hist-ph]) 上午9:47 | physics.hist-ph updates on arXiv.org Authors: Raphael Bousso, Fernando Quevedo, Steven Weinberg Joseph Polchinski (1954-2018), one of the the leading theoretical physicists of the past 50 years, was an exceptionally broad and deep thinker. He made fundamental contributions to quantum field theory, advancing the role of the renormalization group, and to cosmology, addressing the cosmological… Read more →

A Note on Hierarchy of Quantum Measurement Incompatibilities. (arXiv:2001.11326v1 [quant-ph]) 上午9:26 | Bao-Zhi Sun, hi-Xi Wang, Xianqing Li-Jost, Shao-Ming Fei | quant-ph updates on arXiv.org The quantum measurement incompatibility is a distinctive feature of quantum mechanics. We investigate the incompatibility of a set of general measurements and classify the incompatibility by the hierarchy of compatibilities of its subsets. By using… Read more →

A Categorical Reconstruction of Quantum Theory. (arXiv:1804.02265v4 [quant-ph] UPDATED) 上午9:26 | Sean Tull | quant-ph updates on arXiv.org We reconstruct finite-dimensional quantum theory from categorical principles. That is, we provide properties ensuring that a given physical theory described by a dagger compact category in which one may `discard’ objects is equivalent to a generalised finite-dimensional quantum theory over a suitable… 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 →

The Platonic solids and fundamental tests of quantum mechanics. (arXiv:2001.00188v1 [quant-ph]) 上午9:05 | Armin Tavakoli, Nicolas Gisin | quant-ph updates on arXiv.org The Platonic solids is the name traditionally given to the five regular convex polyhedra, namely the tetradron, the octahedron, the cube, the icosahedron and the dodecahedron. Perhaps strongly boosted by the towering historical influence of their namesake, these… Read more →
