    Quantum key distribution without sending a quantum signal by T C Ralph, N Walk

    Published 2015-01-01
    “…If relativistic quantum field theory is considered we show it is possible to distribute an unconditionally secure secret key without sending a quantum signal, instead harnessing the intrinsic entanglement between different regions of space–time. …”

    R-evolving QCD matrix elements by Scimemi, Ignazio, Jain, Ambar, Hoang, Andre, Stewart, Iain W.

    Published 2021
    “…MS, combined with dimensional regularization, is one of the most popular and practical renormalization scheme in quantum field theory. One of the drawbacks of this scheme is however that undesired infrared contributions hide in the short-distance calculations and manifest themselves as the so called renormalon ambiguities. …”

    Pion spectral properties above the chiral crossover of QCD by Peter Lowdon, Owe Philipsen

    Published 2022-10-01
    “…Abstract Spectral functions encode a wealth of information about the dynamics of any given system, and the determination of their non-perturbative characteristics is a long-standing problem in quantum field theory. Whilst numerical simulations of lattice QCD provide ample data for various Euclidean correlation functions, the inversion required to extract spectral functions is an ill-posed problem. …”

    Conformal boundary conditions, loop gravity and the continuum by Wolfgang Wieland

    Published 2018-10-01
    “…Abstract In this paper, we will make an attempt to clarify the relation between three-dimensional euclidean loop quantum gravity with vanishing cosmological constant and quantum field theory in the continuum. We will argue, in particular, that in three spacetime dimensions the discrete spectra for the geometric boundary observables that we find in loop quantum gravity can be understood from the quantisation of a conformal boundary field theory in the continuum without ever introducing spin networks or triangulations of space. …”
