Electromagnetically induced transparency enables the transmission of a laser pulse through an optically dense medium to be manipulated using a control beam. Here this technique is scaled down to a single atom, which acts as a quantum-optical transistor with the ability to coherently control the transmission of light through a cavity. This may lead to novel quantum applications, such as dynamic control of the photon statistics of propagating light fields.
