Rydberg atoms show a variety of extreme properties, including a high sensitivity to external peturbations. We present an experimental setup for measuring molecular chirality with Rydberg atoms as a quantum probe. The goal of the project is to perform chiral discrimination based on far field interaction between chiral molecules and Rydberg dressed cold atoms. Chiral molecules in a supersonic beam will interact with a cloud of ultracold atoms in a MOT while Rydberg dressing will be applied to the atoms. A quantum measurement scheme allows for ultra-sensitive detection of chirality dependent interaction energy shifts.
