We propose an experiment for creating quantum superposition states involving of the order of 10(14) atoms via the interaction of a single photon with a tiny mirror. This mirror, mounted on a high-quality mechanical oscillator, is part of a high-finesse optical cavity which forms one arm of a Michelson interferometer. By observing the interference of the photon only, one can study the creation and decoherence of superpositions involving the mirror. A detailed analysis of the requirements shows that the experiment is within reach using a combination of state-of-the-art technologies.

“…In our experiment helium was refrigerated by a nuclear demagnetization cryostat [21] in a cell with a central cuboid volume (length, 10 mm; width, 10 mm; height, 25 mm) that was connected from two opposite corners to a surrounding annular channel (diameter, 25 mm; width, 1 mm; height, 25 mm). The bottom of the central cuboid was 0.4 mm lower than the bottom of the annulus.…”

Oscillations on free surface of superfluids at the inviscid limit are damped by quasiparticle scattering. We have studied this effect in both superfluids 3 He and 4 He deep below the respective critical temperatures. Surface oscillators offer several benefits over immersed mechanical oscillators traditionally used for similar purposes. Damping is modeled as specular scattering of ballistic quasiparticles from the moving free surface. The model is in reasonable agreement with our measurements for superfluid 4 He but significant deviation is found for 3 He.
