A new optical antenna could improve the efficiency of devices that handle just a few photons at a time, such as quantum computers and quantum cryptography circuits. The antenna, which receives and transmits light in one direction, is a few hundred nanometers in size. With five nanoscopic gold bars of diminishing length sitting across one larger bar, it resembles a directional TV antenna.

Niek van Hulst, a professor at the Institute of Photonic Sciences in Barcelona, Spain, led the development of the nano-antenna. He says it could prove useful for quantum computing and quantum cryptography because it can transmit light in a single direction. Currently, the components used to emit and detect photons for these purposes do so in all directions. "It's very difficult to control where the photons go," he says.
