Abstract:
The focus of my talk is to create a spatial superposition to test the foundations of quantum mechanics and the nature of spacetime in detecting the quantum nature of the graviton in a lab. One of the key game-changing aspects for these experiments is to create a spatial quantum superposition. I will discuss a current-carrying chip design to levitate a neutral nanodiamond in a lab. We will first create a trapping potential and a long trap to create a spatial superposition. In the second design, I will discuss whether we can create a small spatial superposition at the nanometer-to-micron scale for a mass ranging from 10^{-17} kg to 10^{-15} kg.
