The holographic entropy bound is used to estimate the quantum-gravitational discreteness of inflationary perturbations. In the context of scalar inflaton perturbations produced during standard slow-roll inflation, but assuming that horizon-scale perturbations ``freeze out'' in discrete steps separated by one bit of total observable entropy, it is shown that the Hilbert space of a typical horizon-scale inflaton perturbation is equivalent to that of about 10^5 binary spins-- approximately the… Expand

Pattern of perturbations from a coherent quantum inflationary horizon
It is proposed that if quantum states of space-time are coherent on null surfaces, holographic Planck-scale fluctuations of inflationary horizons dominate the formation of primordial scalar curvatureExpand

Models are developed to estimate properties of relic cosmic perturbations with "spooky" nonlocal correlations on the inflationary horizon, analogous to those previously posited for information onExpand
Holographic entropy bounds in the inflationary universe
We introduce the relation between the holographic entropy bounds and the inflationary universe. First the holographic entropy bounds for radiation-dominated universe, radiation-dominated universeExpand
Information from the Beginning
Requiring black hole evaporation to be quantum-mechanically coherent imposes a universal, finite “holographic bound”, conjectured to be due to fundamental discreteness of quantized gravity, on theExpand

This paper shows how increased entropy values from an initially low big bang level can be measured experimentally by counting relic gravitons. Furthermore the physical mechanism of this entropyExpand


Quantum Gravity In De Sitter Space
We discuss some general properties of quantum gravity in De Sitter space. It has been argued that the Hilbert space is of finite dimension. This suggests a macroscopic argument that GeneralExpand

The correspondence between string theory in Anti-de Sitter space and super Yang Mills theory is an example of the Holographic principle according to which a quantum theory with gravity must beExpand

Positive vacuum energy and the N-bound
We argue that the total observable entropy is bounded by the inverse of the cosmological constant. This holds for all space-times with a positive cosmological constant, including cosmologiesExpand
Quantum Information and Quantum Black Holes
A naive view of physics—classical or quantum—would have us believe that an infinite amount of information can be contained in a finite 3-D space. After all, matter can have an infinity of classicalExpand
