    "abstract": "Electromagnetically induced transparency in an optically thick, cold medium\ncreates a unique system where pulse-propagation velocities may be orders of\nmagnitude less than $c$ and optical nonlinearities become exceedingly large. As\na result, nonlinear processes may be efficient at low-light levels. Using an\natomic system with three, independent channels, we demonstrate a quantum\ninterference switch where a laser pulse with an energy density of $\\sim23$\nphotons per $\\lambda^2/(2\\pi)$ causes a 1/e absorption of a second pulse.",
