AB  - Many quantum gravity theories predict spacetime fluctuations at the Planck scale. Neutrinos, which interact only via the weak force and gravity, propagate over long distances without losing quantum coherence. Planck-scale fluctuations would spoil that coherence, damping the flavor oscillation probability over long baselines. This makes neutrinos sensitive interferometers for Planck-scale physics. We present a search for quantum decoherence using 368,071 atmospheric neutrinos detected by IceCube in the energy range 0.5-100 TeV, an order of magnitude higher in energy than any previous decoherence search. We find no evidence for decoherence and set the strongest constraints to date on this class of neutrino decoherence models, improving on previous limits by over an order of magnitude for decoherence rate scaling as E^2 and E^3. These results exclude natural Planck-suppressed decoherence for all energy scalings E^n with 0≤ n ≤ 3, the first such exclusion at the Planck scale for n=3.
