“Weird” computer is made of two layers of organic material

18 May 2010—A team of scientists from Japan and the United States reports that it has figured out how to build a massively parallel computer-like device using organic molecules. But some experts wonder how useful it could be. The new computer, which was described in a recent issue of Nature Physics, is just a couple of molecular layers thick and mimics some aspects of the way the human brain performs calculations.

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.

”We’re doing what people in the Bell Laboratories did in the 1950s,” says Eden Figueroa, one of the physicists involved in the project. ”They were inventing the transistor, and people thought they were crazy. But 50 years later, everyone is using a laptop.” Now, he says, ”we’re inventing the quantum transistor that may be used in computers 30 years from now.”
