Metal tip spouts electrons with an attosecond beat

Electronics could possibly operate with a beat of a few tens of attoseconds in the future. Researchers at the Max Planck Institute of Quantum Optics in Garching near Munich have controlled electrons which gushed from a metal tip a few nanometres across with an accuracy of 80 attoseconds. An attosecond is only a billionth part of a billionth of a second – in this time, light can only travel a distance roughly equivalent to the diameter of an atom.
such a way that the electrons are released by the so-called quantum mechanical tunnel
