Non-Linear Strong Data-Processing for Quantum Hockey-Stick Divergences

Theshani Nuradha, Ian George, Christoph Hirche

Data-processing is a desired property of classical and quantum divergences and information measures. In information theory, the contraction coefficient measures how much the distin…

The Generalized Interval Polynomial of a Poset

Ian George, Karen Yeats

For any finite poset we define a generating polynomial counting upsets, downsets, and their intersection. We investigate the behaviour of this polynomial with respect to poset oper…

The Degree Polynomial

Jason I. Brown, Ian C. George

The degree polynomial of a multigraph is given by $\sum _{v \in V(G)} x^{\mbox{deg}(v)}$. We investigate here properties of the roots of such polynomials. In addition to examin…

A Unified Approach to Quantum Contraction and Correlation Coefficients

Ian George, Marco Tomamichel

The maximal correlation coefficient measures the linear correlation in a bipartite distribution and contraction coefficients measure how much information is lost under a noisy chan…

Quantum Doeblin Coefficients: Interpretations and Applications

Ian George, Christoph Hirche, Theshani Nuradha +1

In classical information theory, the Doeblin coefficient of a classical channel provides an efficiently computable upper bound on the total-variation contraction coefficient of the…

Experimental asymmetric relativistic zero-knowledge proofs with unconditional security

Chen-Xun Weng, Ming-Yang Li, Nai-Rui Xu +6

Zero-knowledge proofs (ZKPs) are widely applied in digital economies, such as cryptocurrencies and smart contracts, for establishing trust and privacy between untrusted parties. Cl…
