Dr. Chiao has proposed an innovative experiment to test the quantum             mechanical nature of a phase factor in the quantum wave equation whose          existence was recently predicted by M.V. Berry of Bristol U.  This              phase factor is acquired by a quantum system upon its adiabatic                 transport around a closed circuit in parameter space, &amp; is a                    topological property of the circuit. Dr. Chiao &amp; collaborators recently         carried out an optical demonstration of the Berry phase in the                  classical limit using polarization rotation in a helically-wound                optical fiber.  The excitement of these experiments, which were                 recently published in Physical Review Letters, was captured in an               extensive news article in the 9/18/86 issue of Nature.  There is                currently considerable controversy that the observed phase shifts are           purely classical in nature. A test of the quantum nature of the phase           through proposed fiber-optic interferometry in the singly photon limit          could establish a novel correspondence between classical and quantum            mechanics. The photon as a particle with spin could acquire a                   topologically nontrivial history dependence of its phase. Chiao points          out several potential novel applications arising from the Berry phase,          such as, in gyroscopy where this new type of optical activity could be          exploited to detect rotations with respect to a fixed inertial frame in         space.
