We describe the thermal and electrical conductivites of quasi-one dimensional
wires across a quantum phase transition between a superconductor and metal
driven by pairbreaking perturbations. Fluctuation corrections to BCS theory
motivate a field theory for quantum criticality. In the quantum critical
region we can compute deviations in the Wiedemann-Franz ratio from the Lorenz
number which will act as a sensitive test of the theory. Time permitting, the
connection of the critical theory to a recently proposed infinite randomness
fixed point will be discussed.
