Holography, Quantum Geometry, and Quantum Information Theory
We interpret the Holographic Conjecture in terms of quantum bits (qubits). Nqubit states are associated with surfaces that are punctured in N points by spin networks' edges labelled by the spin2 1 representation of ) 2 ( SU , which are in a superposed quantum state of spin "up" and spin "down". The formalism is applied in particular to de Sitter horizons, and leads to a picture of the early inf...
متن کاملFrom Liouville Theory to the Quantum Geometry of Riemann Surfaces
• Quantum Liouville theory provides the simplest example for a two-dimensional conformal field theory with continuous spectrum . It can therefore be regarded as a paradigm for a whole new class of two-dimensional conformal field theories which are neither rational nor quasi-rational. • The quantized Liouville theory is related to quantized spaces of Riemann surfaces. This interpretation should ...

متن کاملOn Information Theory, Spectral Geometry and Quantum Gravity
We show that there exists a deep link between the two disciplines of information theory and spectral geometry. This allows us to obtain new results on a well known quantum gravity motivated natural ultraviolet cutoff which describes an upper bound on the spatial density of information. Concretely, we show that, together with an infrared cutoff, this natural ultraviolet cutoff beautifully reduce...
متن کاملIntroduction to quantum information theory
My name is Michael Nielsen, and I work at the University of Queensland on quantum information theory, which is the subject of my talk today. It’s part of a larger subject known as quantum information science, which is being investigated by many people at the University of Queensland as part of the activities of the Center for Quantum Computer Technology. Technical work on quantum information ge...
