A quantum fluid can refer to a cluster of valence electrons moving together after they undergo fermionic condensation. Under extremely high pressures and low temperatures electrons may condense into a quantum fluid. In such a state, electrical current can theoretically flow forever with a complete absence of voltage, meaning that its electric potential does not change, as in a superconductor.(they are like a 5th state of matter) Quantum fluids exhibit the remarkable property of remaining liquid at absolute zero temperature and zero pressure. This effect arises from their large zero-point energy and the small interatomic forces, both of which prevent the formation of a solid phase. A quantum fluid can also refer to a superfluid (made up of atoms). References 1. Lerner, Rita G. and Trigg, George L. (1990). Encyclopedia of Physics. VHC Publishers. 0-89573-752-3.
