    "abstract": "Off-diagonal geometric phases acquired in the evolution of a spin-1/2 system\nhave been investigated by means of a polarized neutron interferometer. Final\ncounts with and without polarization analysis enable us to observe\nsimultaneously the off-diagonal and diagonal geometric phases in two detectors.\nWe have quantitatively measured the off-diagonal geometric phase for noncyclic\nevolutions, confirming the theoretical predictions. We discuss the significance\nof our experiment in terms of geometric phases (both diagonal and off-diagonal)\nand in terms of the quantum erasing phenomenon.",
