Abstract
Recent studies have shown that light can be slowed down substantially and even stopped. In their Perspective, Scully and Zubairy highlight two reports that may help to use slow and stopped light in applications. In the first report, Bigelow et al. show that light can be slowed to a speed of 100 m/s in room-temperature solids. The work should aid the development of devices that exploit slow light. In the second report, van der Wal et al. use slow-light physics to make correlated photon states, which may find application in quantum cryptography.
