We discuss how effectively to stop traveling three-color light pulses in the medium by using three control laser fields at near resonant transitions satisfying electromagnetically induced transparency. This opens a door to the quantum coherent control of multiple traveling light pulses for quantum memory and quantum switching, which are essential components in multi-party quantum optical communications.12 pagesQuantum Physicstext
