• Abstract: There ought to exist a reformulation of quantum theory, even at energy scales much lower than Planck scale, which does not depend on classical time. Such a formulation is required also for the standard model of particle physics, at the low energies at which it is currently observed. We have proposed such a formulation, by replacing 4D Minkowski spacetime by an octonionic space. Doing so allows us to naturally construct spinor states which describe quarks and leptons having properties as in the standard model. We conclude that the aforesaid reformulation of quantum theory helps understand why the standard model is what it is. We do not need experiments at ever higher energies to understand the low energy standard model. Instead, we need a better understanding of the quantum nature of spacetime at low energies, such that the quantum spacetime is consistent with the principle of quantum linear superposition. In the present short review article, we give a summary of our ongoing research programme which aims to address these issues.

• Entropy production due to spacetime fluctuations [0.0]
  We consider a non-relativistic quantum system interacting with gravitational waves. We employ the consistent histories approach to quantum mechanics to define a fluctuation relation for this system. As a result, thermodynamic entropy must be produced in the system due to its unavoidable interaction with the quantum fluctuations of spacetime.

The observation of non-trivial learning properties demonstrated in these benchmarks will motivate further exploration of the quantum-data learning architecture in high-energy physics.

• Relativistic Particle Motion and Quantum Optics in a Weak Gravitational Field [0.0]
  Long-baseline quantum experiments in space make it necessary to better understand the time evolution of relativistic quantum particles in a weakly varying gravitational field. We explain why conventional treatments by traditional quantum optics and atomic physics may become inadequate when faced with issues related to locality, simultaneity, signaling, causality, etc. Adding the effects of gravitation, we are led to Quantum Field Theory in Curved Spacetime (QFTCST) This well-established theory should serve as the canonical reference theory to a large class of proposed space experiments testing the foundations of gravitation and quantum theory.

  We apply the Entropic Dynamics (ED) framework to construct a quantum dynamics for scalar fields in space-time. Using a similar methodology, we construct a theory of quantum scalar fields in flat space-time that is relativistic, but not manifestly so. We consider such a theory and discuss its plausibility as a candidate for a quantum gravity theory.

A precise general law for the time evolution of states replacing the Schr"odinger equation is formulated within the so-called ETH-Approach to Quantum Mechanics.

Here, we reveal that the quantum Hall phase with topological edge states, spectral Landau levels and Hofstadter butterfly can emerge in a simple quantum system. Such systems, arrays of two-level atoms (qubits) coupled to light being described by the classical Dicke model, have recently been realized in experiments with cold atoms and superconducting qubits.
