Computability at the Planck scale
Paola Zizzi
We consider the issue of computability at the most fundamental level of physical reality: the Planck scale. To this aim, we consider the theoretical model of a quantum computer on…
Spacetime at the Planck Scale: The Quantum Computer View
Paola Zizzi
We assume that space-time at the Planck scale is discrete, quantised in Planck units and "qubitsed" (each pixel of Planck area encodes one qubit), that is, quantum space-time can b…
Quantum Computing Spacetime
P. A. Zizzi
A causal set C can describe a discrete spacetime, but this discrete spacetime is not quantum, because C is endowed with Boolean logic, as it does not allow cycles. In a quasi-order…
Ultimate Internets
P. A. Zizzi
In a previous paper (gr-qc/0103002), the inflationary universe was described as a quantum growing network (QGN). Here, we propose our view of the QGN as the "ultimate Internet", as…
The Early Universe as a Quantum Growing Network
P. A. Zizzi
We consider a quantum gravity register that is a particular quantum memory register which grows with time, and whose qubits are pixels of area of quantum de Sitter horizons. At eac…
Emergent Consciousness: From the Early Universe to Our Mind
P. A. Zizzi
In a previous paper (gr-qc/9907063) we described the early inflationary universe in terms of quantum information. In this paper, we analize those results in more detail, and we str…
