Abstract : We make the case that dark energy is not a classical source, but rather the non-classical, quantum gravitational state of extremely light particles with wavelength of the order of Hubble radius. The presence of such particles is motivated by the holographic principle, which shows that the number of fundamental degrees of freedom in the universe far exceeds the number inferred from visible and dark matter. The energy associated with these Hubble scale particles effectively amounts to the source being a cosmological constant consistent with the observed value.
