Quantum physics is very successful in describing nature and developing technology. However, quantum physics had not yet been really understood. Instead, quantization procedures and postulates had been proposed without derivation from more general physics. Now, quantum physics has been derived as a natural consequence of the dynamics of vacuum. These dynamics, in turn, has been derived from gravity and relativity. Thus, quantum physics is a natural consequence of gravity and relativity. In this paper, I derive the dynamics of the vacuum, I derive quantum physics, and I propose a corresponding course of quantum physics.

Quantum theory (QT) is usually formulated in terms of abstract mathematical postulates involving Hilbert spaces, state vectors and unitary operators. In this paper, we show that the full formalism of QT can instead be derived from five simple physical requirements, based on elementary assumptions regarding preparations, transformations and measurements. This is very similar to the usual formulation of special relativity, where two simple physical requirements-the principles of relativity and light speed invariance-are used to derive the mathematical structure of Minkowski space-time. Our derivation provides insights into the physical origin of the structure of quantum state spaces (including a group-theoretic explanation of the Bloch ball and its three dimensionality) and suggests several natural possibilities to construct consistent modifications of QT.

The experience from Quantum Information has lead us to look at Quantum Theory (QT) and the whole Physics from a different angle. The information‐theoretical paradigm—It from Bit— prophesied by John Archibald Wheeler is relentlessly advancing. Recently it has been shown that QT is derivable from pure informational principles. The possibility that there is only QT at the foundations of Physics has been then considered, with space‐time, Relativity, quantization rules and Quantum Field Theory (QFT) emerging from a quantum‐information processing. The resulting theory is a discrete version of QFT with automatic relativistic invariance, and without fields, Hamiltonian, and quantization rules. In this paper I review some recent advances on these lines. In particular: i) How space‐time and relativistic covariance emerge from the quantum computation; ii) The derivation of the Dirac equation as free information flow, without imposing Lorentz covariance; iii) the information‐theoretical meaning of inertial mass and Planck constant; iv) An observable consequence of the theory: a mass‐dependent refraction index of vacuum. I will then conclude with two possible routes to Quantum Gravity.
In this paper, we derive the full quantum mechanics theory and its postulates from a totally classical field theory. We just extend the Lorentz symmetry group of space-time by adding a new simple abelian symmetry, gauge them both, and find the resultant equations of motion. Then, all the postulates of quantum mechanics, including spin and the Planck constant, are derived easily and naturally. The interpretation of quantum mechanics gets new insights. Furthermore, the speed of light constant, the number of space-time dimensions, and the Minkowskian metric are derived as collateral results. all in one piece, however ambitious it may seem, it just works. In short, Quantum mechanics is a classical field theory after all, mathematically proven.
Quantum mechanics is assumed throughout as a fundamental and experimentallyvalidated formalism. This work does not seek to replace or modify its mathematicalstructure. Instead, we investigate whether several well-known quantum phenomenacan be understood as universal consequences of treating quantum systems as opensystems embedded in a structured physical vacuum.Within the Quantum Gravity Theory based on Inverted Relativity (QGT:IR), thevacuum is modeled as a scalar medium with spectral response properties, and all physicalsystems are assumed to exchange energy weakly but persistently with this vacuum.Under these assumptions, we show that quantum decoherence, vacuum-induced noise,hierarchies of state lifetimes, and an effective arrow of time emerge naturally withoutaltering the Hilbert-space formalism, operator algebra, or measurement postulates ofquantum mechanics.A strict methodological distinction is maintained between results that are deriveddirectly from the framework and physical interpretations that provide ontological orconceptual insight without introducing new predictions. The domain of validity of theapproach is carefully delineated, and its continuity with standard quantum mechanicsand quantum field theory is emphasized.
We examine the possible relations between general relativity and quantum mechanics, from the point of view of their representations of space and time, which are different. We refer to our own understanding of space and time, built in opposition to each other from the physical phenomena, and not constituting an a priori external frame. Within a relation-based thinking, we can only compare the phenomena to the other phenomena, and, from this confrontation, space-time frames arise, as drawn by the trajectories of certain phenomena arbitrarily considered in a privileged way. It is within this framework that one must think the possible association of general relativity (which has not the monopoly of space and time) and quantum mechanics (which has not the monopoly of quantization, to be understood from the comparison of two classes of phenomena within a probabilistic approach). The general question to ask is that of possible exchanges between the different points of views, supported by the various possible phenomena, that is to say those on which space and time are defined, and the others. Space and time do not disappear, the points of views are exchanged. These exchanges are made possible by representing space and time, like the other phenomena, by a pair of fields (r, t); r and t are vectors in a three-dimensional space (time is marked by the position of a moving point in the same space as that defining the positions of the ordinary points), as opposed to field pairs (f, g) associated with the other phenomena (such as the pair of the electric and magnetic fields). One may ultimately envisage quantization of space and time; one may also envisage the definition of time and space solely by quantum mechanics. A preliminary and qualitative framework is presented as a basis for future quantitative research.
