Suggestion on Quantum Computer Circuits

Helio V. Fagundes

For quantum computer circuits, it is proposed that they have, besides the presently used compact graphs, an expanded system of subgraphs, in line with the quantum mechanics superpo…

An Infinite Number of Closed FLRW Universes for Any Value of the Spatial Curvature

Helio V. Fagundes

The Friedman-Lemaitre-Robertson-Walker (FLRW) cosmological models are based on the assumptions of large-scale homogeneity and isotropy of the distribution of matter and energy. The…

Closed Spaces in Cosmology

Helio V. Fagundes

This paper deals with two aspects of relativistic cosmologies with closed (compact and boundless) spatial sections. These spacetimes are based on the theory of General Relativity,…

Orbifolds, Quantum Cosmology, and Nontrivial Topology

Helio V. Fagundes, Teofilo Vargas

In order to include nontrivial spatial topologies in the problem of quantum creation of a universe, it seems to be necessary to generalize the sum over compact, smooth 4-manifolds…

The Discontinuous Spatiality of Quantum Mechanical Objects

Helio V. Fagundes

The quantum mechanical wave-particle dualism is analyzed and criticized, in the framework of Reichenbach's concepts of phenomenon and interphenomenon. It is suggested that the dual…

Quantum Creation of a Universe with Quasi-Hyperbolic Spatial Sections

Helio V. Fagundes, Teofilo Vargas

We calculate the probability of creation of a universe with space topology , where is the circle and is a compact hyperbolic surface of genus $g\…
