Energy-free superfast computing developed

LONDON: Scientists have developed a method that can give computers the ability to carry out superfast data processing using light pulses instead of electricity.
The research, published in the journal Nature, shows that magnets can be used to record computer data which consume virtually zero energy. The advance could possibly solve the problem of high energy costs accompanying data processing, according to researchers at the Lancaster University in the UK.
The method replaces electricity with extremely short pulses of light — the duration of which is one trillionth of a second — concentrated by special antennas on top of the magnet, researchers said.
The new method is not only superfast but also energy efficient as the temperature of the magnet does not increase at all.
“The record-low energy loss makes this approach scalable,” said Rostislav Mikhaylovskiy from the Lancaster University.
