Abstract: None of the explanations of quantum gravity that modern physics has come up with have yet to be observed or verified in the lab. As gravity is such a weak force, entanglement is slow enough that systems often decohere before a measurement can be taken. This project attempts to rectify this, searching for a method in which gravitational quantum entanglement can be induced before decoherence. Theoretically, entanglement generation can happen by simply trapping two newtonian masses in harmonic potentials, however, recent papers have shown that using inverted, oscillator potentials will generate entanglement faster. This project investigates how a higher polynomial order inversed potential might generate entanglement even faster, calculate this entanglement time, as well as determine what experimental conditions are required in order to suspend decoherence long enough for a measurement window, getting us closer to a feasible laboratory test of weak field quantum gravity.
