Abstract: Fractional quantum Hall systems (FQH), due to their experimentally observed anyonic topological order, are a main contender for future hardware-implementation of error-protected quantum registers ("topological qbits") subject to error-protected quantum operations ("topological quantum gates"), both plausibly necessary for future quantum computing at useful scale, but both remaining insufficiently understood.Here we present a novel non-Lagrangian effective description of FQH anyons, based on previously elusive proper global quantization of effective topological flux in extraordinary non-abelian cohomology theories. This directly translates the system's quantum-observables, -states, -symmetries, and -measurement channels into purely algebro-topological analysis of local systems of Hilbert spaces over the quantized flux moduli spaces.Under the hypothesis -for which we provide a fair bit of evidence -that the appropriate effective flux quantization of FQH systems is in 2-Cohomotopy theory (a cousin of Hypothesis H in high-energy physics), the results here are rigorously derived and as such might usefully inform laboratory searches for novel anyonic phenomena in FQH systems and hence for topological quantum hardware.
