Why is the conductance quantized?

  1. Mar 8, 2014 #1
    according to the Landauer formula, the conductance is proportional to the transmission probability.

    But the transmission probability is not quantized generally

    So why is the conductance quantized?

    i now see.

    So it is not as specular as magnetic quantization in superconductors
