Abstrakt: 
In a sufficiently strong magnetic field, a cold 2D electron gas forms fractional quantum Hall states. These are prominently characterized by a quantized Hall conductance and the appearance of 1D edge
channels. Certain states, called non-Abelian, are predicted to have exotic particles with potential use for quantum computation. However, unambiguously identifying these states is experimentally challenging since many measurements cannot uniquely distinguish between theoretical candidate states.
In this Master thesis defence, I present how to distinguish between non-Abelian candidates for the 5/2 state with edge transport spectroscopy. My focus lies on computing the heat conductance, the generated noise, and their dependence on the degree of thermal equilibration between the edge channels. I compare these results to recent experimental findings.
