Quantum Mechanical Transistor Promises Photonic Applications

Facebook X LinkedIn Email
Scientists at Sandia National Laboratories in Albuquerque, N.M., have developed a quantum mechanical transistor that may increase the accuracy of optical detectors and energy spectrometers. The transistor takes advantage of a phenomenon described in quantum physics as electrons tunneling from path to path through a normally impenetrable barrier. The atomic-scale effect may take place as fast as a trillion operations a second -- about 10 times the speed of the fastest transistor circuits currently in use. According to its leader, Jerry Simmons, the team has demonstrated working circuits that...Read full article
