• Abstract: Using techniques of p-adic analysis, it is possible to formulate a rigorous version of the quantum mechanics (QM), in the sense of Dirac-von Neumann, consistent with the existence of the Planck length. Such a model cannot be formulated if we use R^{3} as a model for physical space. The experimental testability of physical theories at the Planck scale is currently impossible. Here, we provide an indirect, theoretical argument that shows that the p-adic QM has physical content. We show that a large class of Schr\"odinger equations describes the scaling limits of continuous-time quantum walks on graphs (stochastic automata). These quantum walks appear as fundamental tools in quantum computing. We conjecture that this interpretation is valid in a general framework. The `new theory' does not have Lorentz symmetry, and the Einstein causality is violated. This fact does not contradict the so-called no-communication theorem; such a result requires as a primary hypothesis that R^{4} be a valid model for space-time at the Planck scale. Thus, the no-communication theorem under the discreteness of the space is an open problem.

The formalism for understanding the continuous quantum measurement process on the quantum state has been previously discussed using the Schr"odinger picture. In this work, an equivalent formalism using the Heisenberg picture is developed and applied to the analysis of two optomechanical experiment protocols.

• Non-Heisenbergian quantum mechanics [0.0]
  Relaxing the postulates of an axiomatic theory is a natural way to find more general theories. Here, we use this way to extend quantum mechanics by ignoring the heart of Heisenberg's quantum mechanics. Perhaps surprisingly, this non-Heisenberg quantum theory, without a priori assumption of the non-commutation relation, leads to a modified Heisenberg uncertainty relation.

  This article studies the breaking of the Lorentz symmetry at the Planck length in quantum mechanics. We use three-dimensional p-adic vectors as position variables, while the time remains a real number. We introduce a new p-adic Dirac equation that predicts the existence of particles and antiparticles and charge like the standard one.

• An ontological description for relativistic, massive bosons [0.0]
  Locality holds for the quantum theory, and seems to be fully obeyed also by the classical treatment. We do discuss extensively the distinction between the quantum treatment and the classical one, even though they produce exactly the same equations mathematically. It is suggested to apply this theory for real time quantum model simulations.

The external wave function corresponds to a field that pilots the center-of-mass of the quantum system. The internal wave function corresponds to the interpretation proposed by Edwin Schr"odinger.
