The Hubble tension is analyzed in the framework of quantum cosmological approach. It is found that there arises a new summand in the expression for the total energy density stipulated by the quantum Bohm potential. This additional energy density modifies the expansion history of the early universe and decays faster than radiation in late universe. Similarly to physical models with early dark energy, taking account of this matter source of quantum nature can, in principle, eliminate a discrepancy between the Hubble constant estimates obtained in different approaches. The model been considered allows one to extend the standard cosmology to quantum sector.
