The quantum sieving mechanism through the bilayer membranes calculated for hydrogen isotopes is described. A technique for the determining the potential energy of interaction of a monoatomic membrane with atoms and molecules is presented. The probability density of the distribution of molecules when passing through the membrane is obtained by the matrix method of solving the differential Schrödinger equation. It consists of using the linking technology at the boundaries of the calculated interval. The permeability of a bilayer graphdiyne membrane for hydrogen isotopes H2, D2, T2, and HD is considered. The resonant regimes of the component passage are found and the conditions favorable for the separation of individual components from the mixture are determined. As a result, it has been shown that composite membranes are effective for separation of isotopes in the gas state at cryogenic temperatures
