The Joint Quantum Institute and the University of Maryland have created a transistor that is activated by photon interactions. Enabled by a semiconductor chip, the device is the first single-photon transistor. Astonishingly small, it is quite capable. Millions of these transistors could reside within the space of a grain of salt. Yet, the device is able to process nearly 10 billion qubits per second. The device shows promise in advancing quantum computers. 

Where it all started, the basic transistor.
