We propose a protocol for the preparation of chiral Rydberg states. It has been shown theoretically that using a suitable superposition of hydrogen wavefunctions, it is possible to construct an electron density and probability current distribution that has chiral nature. Following a well established procedure for circular Rydberg state generation and subsequent manipulation with taylored radio frequency pulses under the influence of a magnetic field, the necessary superposition with correspondingly set phases can be prepared. Enantio-selective excitation using photo-ionization circular dichroism is under theoretical and experimental development.
