Local photons

The classical free-space solutions of Maxwell's equations for light propagation in one dimension include wave packets any shape that travel at the speed light. This includes highly-localised remain localised all times. Motivated by this observation, paper builds on recent work Southall et al. [J. Mod. Opt. 68, 647 (2021)] and shows a local description quantised electromagnetic field, which supports such must overcome several no-go theorems, is indeed possible. Starting from assumption basic building blocks photonic are so-called bosons position (blips), we identify relevant Schr\"odinger equation construct Lorentz-covariant electric magnetic field observables. In addition show our approach simplifies to standard quantum electrodynamics when restricted subspace states.
