The conductance quantum is a fundamental physical constant that represents the quantized unit of electrical conductance. It is denoted by \\( G_0 \\) and defined as: \\\[ G_0 = \\frac\{2e^2\}\{h\} \\\] where: - \\( e \\) is the elementary charge, approximately \\( 1.602 \\times 10^\{-19\} \\) coulombs, - \\( h \\) is Planck's constant, approximately \\( 6.
