The Single Photon Switch

Modern electronics is built upon the control of electric charges through an electric field. Computing based on photons rather than electrons, on the other hand, promises significantly faster computation and information processing. An international team of researchers has now developed a theoretical system that would allow single photons to be controlled reliably.

Successful Measurement of the Time Intervals that Enable the Direct Measurement of Electrons in Laser Induced Ionisation

Physicists have worked on the quantum physics description of the tunnelling
effect for 60 years. The group led by Ursula Keller has now for the first time
succeeded in measuring time intervals that enable the direct measurement of
the tunnelling time of electrons in laser-induced ionisation.
