Magneto-gravitational traps use the repulsion of diamagnetic particles by magnetic fields combined with the Earth's gravity to create a highly anisotropic and weak trapping potential. The result is stable trapping at all pressures with static fields alone, but low frequencies of oscillation seemingly make quantum behavior unreachable. We report on progress towards observing the quantum limit of the motion by optical measurements of the particle position on time scales short compared to the oscillation period of the motion, making the behavior approach that of a free particle. We also report the use of a trapped particle as an accelerometer with remarkable sensitivity.
