- Abstract: Quantization of the gravity remains one of the most important, yet extremely
illusive, challenges at the heart of modern physics. Any attempt to resolve
this long-standing problem seems to be doomed, as the route to any direct
empirical evidence (i.e., detecting gravitons) for shedding light on the
quantum aspect of the gravity is far beyond the current capabilities. Recently,
it has been discovered that gravitationally-induced entanglement, tailored in
the interferometric frameworks, can be used to witness the quantum nature of
the gravity. Even though these schemes offer promising tools for investigating
quantum gravity, many fundamental and empirical aspects of the schemes are yet
to be discovered. Considering the fact that, beside quantum entanglement,
quantum uncertainty and complementarity principles are the two other
foundational aspects of quantum physics, the quantum nature of the gravity
needs to manifest all of these features. Here, we lay out an interferometric
platform for testing these three nonclassical aspects of quantum mechanics in
quantum gravity setting, which connects gravity and quantum physics in a
broader and deeper context. As we show in this work, all of these three
fundamental features of quantum gravity can be framed and fully analyzed in an
interferometric scheme.
