    "abstract": "We report an experimental demonstration of photon switching by quantum\ninterference in a four-level atomic system proposed by Harris and Yamamoto\n(Phys. Rev. Lett. 81, 3611 (1998)). Quantum interference inhibits single-photon\nabsorption but enhances third-order, two-photon type absorption in the\nfour-level system. We have observed greatly enhanced nonlinear absorption in\nthe four-level system realized with cold 87Rb atoms and demonstrated fast\nswitching of the nonlinear absorption with a pulsed pump laser.",
