The circulating light undergoes constructive interference, forming discrete resonant modes \u2013 or so-called degenerate states \u2013 with similar energies.<\/p>\n<p>The number of modes is dependent on the ratio between the light\u2019s wavelength and the circumference of the resonator \u2014 meaning that, in theory, a spherical object with a circumference tens of microns in size could support hundreds of modes of either visible or near-infrared light. In practice, however, achieving such hyperdegeneracy has proven impossible with conventional fabrication techniques. This is because even a single stem supporting the sphere will reduce the object\u2019s symmetry and thereby reduce the extent of the potential degeneracy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cHyperdegeneracy\u201d could be used in quantum computing.
