Virtual photons found to reduce superconductor performance, study shows
A study in superconductors has found that “virtual photons” that do not physically exist can reduce performance, though it is closer to an experimental test of quantum mechanics than a direct route to high-temperature superconductors. The research, published in Nature, used boron nitride and the kappa-ET superconductor. When boron nitride was layered on the material, its ability to expel magnetic fields weakened, while other materials or similar superconductors showed no change.
