We thank S. Dürr for contributions in the early stages of this project and Z. Zhang for noticing a typo in our final result for . In addition, L. L. thanks M. Benayoun, C. Davies, F. Jegerlehner, M. Knecht, C. Lehner, E. de Rafael, and R. Van de Water for informative discussions. Computations were performed on JUQUEEN and JUROPA at Forschungszentrum Jülich, on Turing at the Institute for Development and Resources in Intensive Scientific Computing (IDRIS) in Orsay, on SuperMUC at Leibniz Supercomputing Centre in München, on Hermit at the High Performance Computing Center in Stuttgart. This project was supported, in part, by the OCEVU Laboratoire d’excellence (ANR-11-LABX-0060) and the A*MIDEX Project (ANR-11-IDEX-0001-02), which are funded by the “Investissements d’avenir” French government program and managed by the “Agence nationale de la recherche” (ANR), by the DFG Grant No. SFB/TR55, by the Gauss Centre for Supercomputing e.V and by the GENCI-IDRIS supercomputing Grant No. 52275. R. M. was supported in part by a joint Ph.D. fellowship from the Centre national de la recherche scientifique (CNRS) and the Commissariat à l’énergie atomique et aux énergies alternatives (CEA).

N2 - We compute the leading, strong-interaction contribution to the anomalous magnetic moment of the electron, muon, and tau using lattice quantum chromodynamics (QCD) simulations. Calculations include the effects of u, d, s, and c quarks and are performed directly at the physical values of the quark masses and in volumes of linear extent larger than 6 fm. All connected and disconnected Wick contractions are calculated. Continuum limits are carried out using six lattice spacings. We obtain aeLO-HVP=189.3(2.6)(5.6)×10-14, aμLO-HVP=711.1(7.5)(17.4)×10-10 and aτLO-HVP=341.0(0.8)(3.2)×10-8, where the first error is statistical and the second is systematic.
