Quantum conductance is the observed change, in discrete steps, of the electrical conductance in an electrical element. The purposes of the project are to build a circuit similar to Foley et al. to show quantum conductance, to build a display for the circuit to show future students quantum conductance, and to design a laboratory experiment for PH 2651 so that students can repeat the experiment for themselves. The histogram of the conductance steps showed that majority occurred in integral multiples of the quantum conductance, which is (2*e^2)/h = 7.75*10^-5 siemens, but half and quarter multiple steps were also seen. Due to time constraints, the designing of the PH 2651 laboratory experiment was not done.
