14 May 2010—Physicists at the Max Planck Institute of Quantum Optics, led by Gerhard Rempe, have created a system based on a single atom that they’re calling a ”quantum optical transistor.” The transistor could someday serve as part of a quantum computer or as a node of a quantum data network.

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.
