Abstract
The change in the phase of a beam of light produced by a cyclic change in its state of polarization is an example of the geometric phase tha t can be verified by interferometric measurements. This paper presents a quantum-field theoretical analysis of the geometric phase interfero meter in the limit of a small photon number, as well as some experimen tal results that confirm that the optical effects due to the geometric phase persist down to the single-photon level.
