• Abstract: Formulating a quantum theory of gravity lies at the heart of fundamental theoretical physics. This collection of lecture notes encompasses a selection of topics that were covered in six mini-courses at the Nordita PhD school "Towards Quantum Gravity". The scope was to provide a coherent picture, from its foundation to forefront research, emphasizing connections between different areas. The lectures begin with perturbative quantum gravity and effective field theory. Subsequently, two ultraviolet-complete approaches are presented: asymptotically safe gravity and string theory. Finally, elements of quantum effects in black hole spacetimes are discussed.

  In quantum gravity theory, a state-dependent gravitational potential introduces nonlinearity into the state evolution. 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.

• Quantum-information methods for quantum gravity laboratory-based tests [0.0]
  We review the nascent field of information-theoretic methods applied to designing tests of quantum gravity in the laboratory. We shall focus mainly on the detection of gravitational entanglement between two quantum probes, comparing this method with single-probe schemes. We shall also highlight the role of general information-theoretic principles in illuminating the search for quantum effects in gravity.

• 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.
