From: Proposal for a quantum mechanical test of gravity at millimeter scale
The experimental setup for testing parity invariance of small scale gravity using two Josephson junctions and a gravitational source with a chiral configuration. Cylinder 1 is placed at at the midpoint of the line connecting of the two JJs along the y axis, while Cylinders 2 and 3 are placed above and in front of Cylinder 1 along the z and x axes respectively. Besides, Cylinder 2 and 3 should be made of different materials with different weights.
