      abstract     = {Modern particle physics experiments, e.g. at the Large
                      Hadron Collider (LHC) at CERN, crucially depend on the
                      precise description of the scattering processes in terms of
                      the known fundamental forces. This is limited by our current
                      understanding of the strong nuclear force, as quantified by
                      the strong coupling, $\alpha_s$, between quarks and gluons.
                      Relating $\alpha_s$ to experiments poses a major challenge
                      as the strong interactions lead to the confinement of quarks
                      and gluons inside hadronic bound states. At high energies,
                      however, the strong interactions become weaker ('asymptotic
                      freedom') and thus amenable to an expansion in powers of the
                      coupling. Attempts to relate both regimes usually rely on
                      modeling of the bound state problem in one way or another.
                      Using large scale numerical simulations of a first
                      principles formulation of Quantum Chromodynamics on a
                      space-time lattice, we have carried out a model-independent
                      determination of $\alpha_s$ with unprecedented precision.
                      The uncertainty, about half that of all other results
                      combined, originates predominantly from the statistical
                      Monte Carlo evaluation and has a clear probabilistic
                      interpretation. The result for $\alpha_s$ describes a
                      variety of physical phenomena over a wide range of energy
                      scales. If used as input information, it will enable
                      significantly improved analyses of many high energy
                      experiments, by removing an important source of theoretical
                      uncertainty. This will increase the likelihood to uncover
                      small effects of yet unknown physics, and enable stringent
                      precision tests of the Standard Model. In summary, this
                      result boosts the discovery potential of the LHC and future
                      colliders, and the methods developed in this work pave the
                      way for even higher precision in the future.},
