Is one Trillionth of a second fast enough for a switch?

US Department of Energy researchers at the SLAC lab have set a new record for switching speed.
Scientists using SLAC's Linac Coherent Light Source (LCLS) X-ray laser found that it takes only 1 trillionth of a second to flip the on-off electrical switch in samples of magnetite, which is thousands of times faster than in transistors now in use. The results were published July 28 in Nature Materials.

    No worries. Happens to VoiCE authors regularly. 😀

    Hey #-Link-Snipped-# We have our first sight of the 1THz processor mate

    IF a switch is that fast in the initial level the rate of processing can further go into the Sub nano sec barrier in the next few years

    #-Link-Snipped-# It's not related to 1THz clock frequency of processor. The transistor switching is increased, so there is improvement in speed, but 1 THz still not possible, trust that.
