    "abstract": "Some recent ideas concerning Pancharatnam\u0027s prescription of relative phase\nbetween quantal states are delineated. Generalisations to mixed states and\nentangled two-photon states are discussed. An experimental procedure to test\nthe geometric phase as a Pancharatnam relative phase is described. We further\nput forward a spatial split-beam dual to Pancharatnam\u0027s relative phase.",
