Abstract:Creating a massive spatial quantum superposition, such as the Schrödinger cat state, where the mass and the superposition size within the range 10-19 - 10-14 kg and Δx ∼ 10 nm - 100 μm, is a challenging task. The methods employed so far rely either on wavepacket expansion or on a quantum ancilla, e.g. single spin dependent forces, which scale inversely with mass. In this paper, we present a novel approach that combines gravitational acceleration and diamagnetic repulsion to generate a large spatial superpositi… Show more
